Irrelevant.
This is a thread about showing "¬ notation for not?" (and similar),
a thread started by that question from Clément. My comment is about
one consideration for such a proposed feature.
My point is separate from _your_ question, but there is no reason
to fork discussion off my point off from Clément's proposed feature,
with which it is concerned. I restored the Subject line.

Yes, of course. It is not aliasing of symbol values (function or
variable). It is, as you say, a "visual clobbering". Visual name
capture.

There is nothing inherently ephemeral in the nature of such functions
or variables.
This is not limited to any particular function or variable (e.g. `not').
Any function or variable could appear in `lisp-prettify-symbols-alist',
and it could be associated with any prettifying string.
The possibility of a visual name capture needs to be considered before
this feature is rolled out.
