Makes sense. I've tagged the bug as moreinfo for now, but barring a compelling use case I'm also leaning towards closing this as wontfix.

>> Use `warn` instead of `message`.
> Stefan, what do you think? Should the below patch be installed?
Still not a fan for the same reasons, plus:
- The real `nadvice.el` was added to Emacs-24.4, released 9 years ago,
and this forward compatibility was first released 5 years ago, so the
need for the library is becoming rare and its functionality proved
adequate for 5 years already.
- (intern (format "%S" func)) can collide with another library
doing something similar, so better use something like
(intern (format "nadvice--%S" func)) just to be on the safe side.
Daan, is there a specific use-case that motivates you to want to pass an
anonymous lambda to this compatibility library?
Maybe I could be convinced by a good use-case.

I'm not a big fan of this approach, and I usually recommend to use named
functions for advice anyway (avoids all kinds of problems like the
`advice-remove` failing to remove, or the equality test taking too much
time, ...).
IOW I'd rather align the "real nadvice.el" with the one in GNU ELPA than
the other way around in this respect.
