They are unsigned 16-bit for now. That means 65K maximum. I think the
data-type is specified by POSIX, so you'd need an alternate interface to
use 32-bit ones. I said 30,000 because I don't know if all tools treat them
as unsigned. I don't know if LIBC 6 addresses 32-bit UIDs and GIDs. When you
get to 80K users, one would hope you have a hashed password file rather than
the flat file we currently use.
All of this is fix-able, without too much trouble, if someone is motivated.
