Is C++ capable of deprecating or simplifying anything?

Honest question, haven't followed closely. rand() is broken,I;m told unfixable and last I heard still wasn't deprecated.

Is this proposal a test? "Can we even drop support for a solution to a problem literally nobody has?"

How is rand() broken? It seems to produce random-ish values, which is what it's for. It obviously doesn't produce cryptographically secure random values, but that's expected (and reflects other languages' equivalent functions). For a decently random integer that's quick to compute, rand() works just fine.

It cannot be called safely from a multi-threaded application for one
