but this is irelevant here.

Not "a pass and a failure". A DKIM pass and SPF pass.

But when the SPF is not aligned, DMARC wording requires sending report for 
"fo=1", because of RFC 
	something other than an aligned "pass" result.

reporting 2 passes but inaligned is non-sense and quite common for mail 
forwarding, and mailing lists, including this one.

I did a mistake before and corrected it:

Wording of fo=0 is fine, report is only send for failed DMARC check.
The unaligned SPF is only issue when DKIM fails.

So, generally do you recommend us not to follow RFC and risk possible issues 
that are currently unseen?
I prefer fixing the RFC instead.
