Maybe there's something obvious I'm missing, but in a graphical emacs
=2Dq, I can't see a zero length active region in the text at all. That is,
after activating it with C-SPC or a non-dragging mouse-1 button press, I
can't see a single pixel around point changing to indicate the region. I
even tried it after considerably enlarging the font with 'C-x C-+ + + +
+ ...'.
(On the other hand, zero-length rectangular regions, created with C-x
SPC, are properly indicated with a thin vertical line, but we aren't
talking about rectangular regions here.)

This use case is, of course, still supported by my patch.
I was talking about the very specific zero-length region, active for the
duration of a non-dragging mouse-1 button being held down. My patch
affects only this specific use-case
>> If you want to create a zero-length region that stays active after

Another unrelated thing to consider is the current behaviour of
clicking/dragging C-M-mouse-1. It doesn't activate a rectangular region
until the user drags C-M-mouse-1. In fact, if the user only does a
non-dragging C-M-mouse-1 click, the rectangular region is never
activated, only the point moves. You can try experimenting with
C-M-mouse-1 and see, if this is really the opposite of the behaviour we
want.
In essence, my patch tries to make behaviour of mouse-1 region
activation more similar to C-M-mouse-1 rectangular region activation.
(Emacs build info follows, since the non-display of zero-length
non-rectangular regions in the text could be dependent on build
configuration.)

(I'm assuming that by "show regions of zero length", you mean that the
"Copy text" toolbar icon is enabled.)
I hope I'm not arguing semantics too much, but my patch doesn't actually
hide an (active) region of zero length, it prevents one from being
activated.
It only prevents it in the specific case of a non-dragging mouse-1
click, which makes quite a lot sense to me. The current behaviour of a
non-dragging mouse-1 click is that the zero-length region is only active
for the duration of the mouse button being held down. Once the button is
released, the zero-length region is deactivated, which makes it not very
useful, as far as I can see. For example, pressing M-w or C-w during the
mouse button being held down doesn't seem to work on the correct
zero-length region and you can't click on the "Copy text" toolbar icon
(maybe you could in a multi-pointer setup, but that's a pretty bizarre
use-case).
If you want to create a zero-length region that stays active after
releasing mouse-1, you have to drag the mouse a little first to make the
region length non-zero and then drag the mouse back to the starting
position to make the region length zero again. This use case is still
supported by my patch.
(Perhaps I missed some use-cases of a zero-length region active during a
non-dragging mouse-1 button hold. If you know any, please let me know
about them.)
This, together with the fact that it reduces the "flicker" from the
original message, makes me insist on the patch.
Best regards.

Well, maybe we could try a bit harder to reduce the flicker for ordinary
non-dragging mouse-1 clicks. One idea could be to prevent down-mouse-1
from activating mark until the region becomes non-zero length, so
something like this patch.
