I still don't understand well your suggestion, but I began to feel like
that a new framework is suitable for the current topic.

0. Most users who customize `TeX-insert-macro-default-style' to
   `mandatory-args-only' want to skip optional arguments for only a
   limited set of macros, not all the macros. (I guess so, at least I
   am such a user.)
1. Introduce a new user option holding macro names which the user wants
   to skip query about optional under usual circumstances (just like
   `TeX-insert-braces-alist'.)
2. In principle, all users don't customize
   `TeX-insert-macro-default-style' (i.e., keep it as
   `show-optional-args'.)

Then,
[a] Each user has to remember only a few macros that he/she registered
in the new option and to type C-u before C-c C-m for exceptional cases
which do need optional arguments.
[b] The user always benefits from query of optional args when entering
environments by C-c C-e. 

I consider implementing such feature in AUCTeX when I have more spare
time :-)
