I don't think this feature exists in Samba, because in order to be able
to create a file in a Unix directory, you need write permission on the
directory, which also allows you to delete files. It's been a while but
AFAIR Netware has Delete and Write as separate rights and I think NT
has the same. As you pointed out, it's not terribly useful, except to
stop accidental deletions.
Unix file permissions have historically been much less granular than
other OS such as VMS or Netware. Using ACLs allows for finer control of
file permissions, and this document

might be helpful.
