It is not only *not* a misuse, it is one of the intended uses,
one might say the most important intended use.

In general, no. If there is a fair chance that something will become
part of Unicode, we usually don't register it. There are exceptions,
like Tengwar and Cirth.

(In truth neither of us has had much time to process new registrations
lately. Arse longa, vita brevis.)

I suspect that it would be unusual to reject a random documented character from
a well-established set. More likely (though not very likely) would be
to reject the whole coding model, in which case all bets would be off.
