I just sent this off to ietf-822 and MAAWG's "techincal" list.
You should also send it to the "message headers" expert review
list when the I-D is in a state where its ABNF passes validation.
Ad 2, I'm no big Received-SPF fan, but it's certainly defined in
an RFC, registered (1), and implemented for some years now (2),
it even got a related erratum (3).
On the "message headers" review list (4) you could already ask
for a provisional registration of "Authentication-Results" until
the I-D is fleshed out (5) and approved resulting in a permanent
registration.
