An interesting side effect is that it would also suppress bounce messages

So, yeah, if the SSP associated with the MailFrom says
"rfc2821.MailFrom" must match a DKIM signature, or somesuch, then a
mailing list that inserts its own MailFrom, without adding its own
signature, could break bounces.
I wouldn't worry too much about that scenario, since if anyone sets that
flag, everyone will be throwing away his mailing list mail anyway.
I think this depends upon the definition of 'this flag' and what range of
assertions is permits. If it is a one-bit flag, then you are no-doubt correct.
