The third alternative is, of course, to claim that the WG is now convinced
that it's acceptable for an IPP client to be unable to print on any
printer that requires non-shared-secret authentication.
This did not seem to be the consensus in Washington, but after all,
the list, not the meeting, is the final arbiter of IETF WG consensus.
Remember - you are the domain experts who are supposed to know what the
requirements for a print protocol are; the IESG requirement is that:
- It's possible for all conformant implementations to be able to
interwork, if configured to do so
- Whatever functions must be implemented use neither cleartext passwords
nor encumbered technology, if possible
If ability of a client to print on a TLS-only-configured printer is not
in your requirements set, then that should not be a requirement.
