The XFS version of these man pages, eg. acl_set(2), say...

CAVEAT
       This  ACL system call can be considered a temporary proto-
       type solution and may be altered for a  more  generic  ACL
       solution in the future.

There are people working on merging the APIs, of course -
as Christopher Lambert would say "there can be only one".
The initial version is pretty much a straight port of the
corresponding IRIX code, to get something up and running.

Indeed, and that has been happening for awhile now.

cheers.
