I started on it, but stopped due to lack of time.

FreeBSD is somewhat neglected too, but from a much better starting point
than open/netbsd. I fix know things once in a while, but don't use it
day-to-day anymore. FreeBSD is now a LLVM system, but I only did minimal
fixes for that.

I had it on a mini G4 1.25.

Most BSDs have syscalls that have an interface similar to a C function, and
often close the the (2) call of the same name. This is where the similarity
Regularly older calls are replaced by newer calls, but while this is an
organic process, but unfortunately it doesn't happen in all of the BSDs at
the same time or even at all.
Darwin used the libc port from the beginning, so doesn't share the syscall
oriented stuff. And afaik most (3) definitions don't change that much.
I don't think there are general rules, best is to discuss it one specific
issue at a time with the relevant maintainers.
