Before more review,just to confirm:
1) draft-crocker-dmarc-author
A proposed new 5322.Author header?
Yes.
Is is required to be hash bound to DKIM signature?
No. In fact the DKIM requirement to include From: in the set of
hash-bound text was a last-minute imposition by an area director, rather
than a functional need set by the working group or larger community.
That said, of course I'd expect signers to choose to include it.
Will be make it a MUST NOT modified NOR rewrite it?
No idea where this would be mandated or why.
2) draft-crocker-dmarc-sender
A proposal to somehow shift DMARC to DNS UP the sender domain for
DMARC policy?
"DNS UP"?
It's a proposal to have DMARC use the Sender: field, in preference to
the From: field.
Does this mean the Sender header is now required to be hash bound to
the signature?
cf, above, about the nature of the requirements. Again, it would make
sense to bind it, but mandating is a separate issue.
