You can have it if you want it. login.conf(5):
Name Type Default Description
[...]
tc string A "continuation" entry, which
must be the last capability
provided. More capabilities are
read from the named entry. The
capabilities given before tc
override those in the entry
invoked by tc.
Add a trailing ":tc=....:" whereever you want. TCs also cascade.
My "staff" stanza has tc=users which in turn has tc=default.
