the vast majority of email goes from A to B and never goes anywhere else
why would a BCP need to say anything about that ?

many local policies are irrational -- but they are local and no BCP will
make any difference to that one way or another

I'm sorry, I missed the text that you are proposing. Please could you
repeat what it was... if it was along the lines of "local policy MUST
be something or other" that is clearly nonsense because that would make
what is being described something other than "local policy"

ah right you are proposing something ... but you seem to have missed out
the definition of what a "re-originating service" might be, you are
tying it to DMARC (which seems problematic), you have not explained what
"functioning" means in terms of an abuse contact (whatever that is)
[[and note that RIPE have been tying themselves in knots for years for
this issue in respect of IP address allocation]] ... and finally I am
unsure what a Sender ADMD originator might be.
