If you are arguing for having a feature that marks some portion of buffer text read-only, then we already have that: the 'read-only' text property. The issue in this discussion is whether we should _also_ have a similar overlay property. (Please don't cross-post to the bug tracker and to emacs-devel.)

Hi, I just realized that this idea could be /extremely/ useful. Here's the case: I start a clock in Org-mode (C-c C-x C-i), and an entry with the starting time is added in the :LOGBOOK: drawer (and btw, it is invisible). While working on the file, I hit C-/ (undo) once too many, and the entry disappears (and this fact is still invisible to me!). Then, after some more work, I stop the clock only to see "org-clock-out: Clock start time is gone", and my clock is still going on (!). While the last thing (about the clock still going on) is probably an Org-mode bug (I'll propbably report it later "officially", I'm now Cc-ing this message to the Org-mode ML), the whole experience (and yes, it happened to me) is /very/ confusing. When read-only properties and masking are here, Org could just mark the half-done entry as read-only. I suspect that trying to undo it would perhaps trigger some error, which could be confusing, but it would be still better than silently removing a vital information.

I envision "LaTeX-mask-environment", and bam! query-replace does not touch verbatim, for instance. That could be very useful! I did something similar with texmathp and math mode, but I like your approach with "masking".

I think read-only overlays could be very useful. For example:
1. Create a command called `mask-regexp'. It creates read-only overlays for
matching text throughout the buffer.
2. There should also be a way to add manual masks, using `mask-region'.
3. Now use `replace-string' or any other command to bulk transform text.
However, masked text is not changed.
4. Then execute unmask-all, and the mask disappears.
This method of editing is key to video editing workflows. I think the only
reason I never thought to use it in Emacs is because it's never been there
(and so never occurred to me until now).

Not necessarily. This is not the same, of course, but compare Dired to Wdired: the same text is sometimes read-only and sometimes not, and it does make a lot of sense. Another possible use-case: a feature like narrowing, but not making some text invisible, but read-only instead. (This might actually be useful, e.g. in Org-mode.) Of course, you could do this with text properties and not overlays, but what I'm saying is that the assumption "it [is] strange to make certain text read-only temporarily. If it isn't supposed to change, it should never change, right?" is false in general, even in current stock Emacs.

I don't remember why I wrote that. It was 6 years ago. My guess is
that I considered it strange to make certain text read-only
temporarily. If it isn't supposed to change, it should never change,
right?

Do I need to? There was an old discussion of this http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01598.html In that discussion, you said: It is no accident that read-only works only as a text property. It is tested for in textprop.c only as a text property. I am not sure that a read-only property on an overlay makes much sense. It is a strange thing to do. So I will fix the documentation. I'm asking if you still think the same. If so, perhaps you could try explaining why you do (in that old discussion, you said it was hard for you to put this into words). Thanks.

If I create an overlay in a buffer and set the 'read-only' property to
t, it seems to make no difference, and I can still make changes to the
text in the region where the overlay is active. Setting other overlay
properties does have an effect. Setting the read-only property as a text
property however works as expected.
To demonstrate:
1. Type some text in an empty buffer.
2. (setq overlay (make-overlay 1 10)) ; Creates an overlay in this
buffer between positions 1-10 named 'overlay'
3. (overlay-put overlay 'read-only t) ; Applies the read-only property
to this overlay.
4. Type some characters at the beginning of the buffer. Emacs doesn't
complain that the text is read-only, and text is edited as normal.
I do this instead:
(put-text-property 1 10 'read-only t) ; Apply the read-only property
as a text property rather than an overlay
Now if I try typing text in the same region as before, Emacs prevents me
from doing so and says 'Text is read-only'.
