I think they intentionally removed the system.nfs4* in Fedora-42 because commands like

Yes, the removal in 2019 was due to a suggestion[1] by Pádraig, which
Kamil Dudka was a bit dubious about[2] but went ahead and did anyway[3].
I'll cc Kamil to see whether he has further comments now.
What we can (and should) do is a check whether the ACLs detected are primitive
(i.e. no ACLs at all) and in this case, just skip the ACL copy.
The Gnulib patch[4] I recently installed does something like that,
except that for efficiency in the non-NFS case it checks whether the
ACLs are primitive only if the ACL copy (via attr_copy_file or
attr_copy_fd) fails with EOPNOTSUP.
With [4] in place, I guess Pádraig's point is that Bruno's older Gnulib
patch[5] is no longer needed. Although I'm not sure about that, I
confess that I'm a bit lost.
What a mess, huh?
