Unaligned signatures are orthogonal/irrelevant to DMARC. They may be useful
in other contexts. In the DKIM standard, signatures mean that the signer is
asserting some (unspecified) responsibility for the signed message. That
may be useful for some reputation systems.

Yes, it could have multiple causes.
I was just trying to elucidate a reason why unaligned signatures are
needed.
Instead I conclude that one best aligned signature is all that is needed
for reporting. Not 100, not 10, just 1.

This is incorrect. SPF FAIL with DMARC PASS can simply be an indirect mail
flow. It might also be an incorrectly configured SPF record.
