I presume you mean "required", not "allowed".  POSIX already allows "=="  (several POSIX shells currently implement it), it's just not *required* in test/[.

Which means there's no need to wait; "==" can be added as an aid to users, whether or not it's in POSIX (yet).

It's not clear to me that "[[" will be added.  That was proposed early on as an idea, but to my knowledge one was proposed any specific text to actually *do* that, and it was rejected last time.  On the other hand, "==" has already been proposed, and most of the discussion seemed to think it reasonable.

Right.  Many existing scripts depend on "==", not "=", and its implementation is trivial.
