Looks like the PROTOCOL_NT1 check goes all the way back to when the
spoolss notification backchannel support was initially added.
We could change the check to (>= PROTOCOL_NT1), but given that modern
clients usually don't accept the backchannel connection, I'd consider
it of little value.
@Thomas, if you're willing to test backchannel notifications against
an SMB2+ print client, I can send you a 4.1 based patch or rpm.
