I think the most natural place is where we describe how to construct
menus.

If this is a private convention of elisp-mode, we don't have to codify
it.

So maybe instead of conventions we should have recommendations, with
explanation why following that could be useful in some situation.
Then let Lisp programmers decide what they want.
