FWIW, the Postgres project maintained C90 compliance for years too.
We dropped that and started to require a C99 compiler as of last
year's release (12.0), and we have received exactly zero push-back.
We are still pretty conservative about it, for example we discourage
//-style comments; but that's for cosmetic reasons not toolchain ones.

I concur with your thought that maintaining C90 compliance of the
generated code might still be worth something.  But allowing C99 in
the compiler really shouldn't be a problem.
