History.  I knew the Solaris ACL API much earlier than I learned about
the POSIX ACL API, and the fact that POSIX 1003.1e was never really
finalized as a standard, but rather withdrawn while still being a draft
back in 1999 didn't give me any confidence that it's worth to implement.
Above all, the Solaris API is much simpler than the POSIX draft.

Having said that, I have no problems if somebody implements the POSIX
API in Cygwin additionally to the Solaris API, but personally I don't
see any advantage.  ACL-aware applications most often support both APIs
on the source level.
