Hi Augusto,
For what it's worth, I've always just done what Arash suggests when
RefTeX gets out of sync, and haven't had any issues with it that I can
remember. (To be fair, my use cases haven't exactly been exotic.)

The only thought I have is that it sounds like a new major mode would
be overkill for what you need here. I would think that a variable or
defcustom might do the trick, or at most maybe a minor mode? When
navigating code I really want to be able to follow the commands to
their source no matter whether the command is internal or for users,
though I can see how in a code-completion setting you might want to be
able to separate the two more cleanly. Obviously, I'm not the person
you need to convince about all of this -- that would be Arash and the
emacs maintainers, themselves.
Best,
David.
