Not at all. It's a half-common need (tho most people don't realize
that other frames could be involved so they just use
save-window-excursion thinking it'll undo any damage).

Ah, indeed it's simpler. It does have the disadvantage of relying on an
obsolete variable, tho.

Of course a real fix is to change the code so that it provide
a "non-displaying" variant, but Jorge often doesn't have the necessary
control over that code. In the case of lisp--company-doc-buffer (in
lisp.el), Jorge actually does have this control but doesn't have the
energy to "do it right".
(1) uses an obsolete var.
(3) binds a user variable, which is bad karma.
(2) is good, but the question remains: "bind it to what?". You did
provide a answer to that question, admittedly, but it's a bit
longwinded, I think we should have a simpler answer.
Maybe we should define a new macro `with-inhibit-window-changes' which
could replace save-window-excursion for those uses (it might use
save-window-excursion internally, just in case, but would also try to
prevent creation of frames and window changes in other frames).
