Thanks for pointing me back to the draft.
I now see I was somehow giving the Identifier Alignment part of the
DMARC spec an "indepedent life" of its own.
One of my test was considering alignment independently of the
existence of the DMARC policy and the "invalid" result surprised me.

It could be possibly argued that the "Identifier Alignment" concept
could stand alone, but in the DMARC context, I understand it is not
relevant by itself.

Kind regards,
