I agree - I had submitted a separate one for the copy problem (where I see
four or five obvious enhancements that could use group discussion
and from looking at github projects see some earlier presumably
abandoned updates to cp to address some of them).

But for additional file utilities - it would make sense to have a short session
to discuss those - NFS would likely have similar requirements to SMB3
(and even some other fs) for that.  What other file utilities besides the
copy ones are the ones that NFS users complain most about not having or
needing to improve?
