POSIX.1e implementation is too old
Our posix1e(3) implementation is too old and not compatible with any
recent enough piece of software.

It never left draft status, yes. I don't understand all the relationships
between posix.1e, all different ACL and extended attributes
implementations, but the fact is that ACL's and extended attributes are
supported nowadays filesystems.
But we happen to have sys/extattr.h and friends no thirdparty software
supports. A lot of such software breaks though if it relies only on
existance of headers.
