I absolutely disagree with your premise, and I think the others have
been saying that as well.

DMARC has *nothing* to do with performing authentication; it's about
publishing policy on the sender side and choosing to comply with
published policy on the receiving side.  DMARC *uses* authentication
that's provided by SPF and DKIM, but DMARC does not, itself, do
authentication.

Alignment is not authentication: alignment is checking whether the
domain that was authenticated (via SPF or DKIM) is "aligned" with the
domain claimed in the message, and that is used in the policy
evaluation.  It's not helpful to claim that any of this is a
"gimmick", to say that people are "want to ignore" problems, nor to
put forth straw-man arguments about obviously silly alignment
algorithms.

No one is ignoring your proposed requirement; we're all responding to
it.  We just disagree with you.  We think you're wrong.
