Looks like the relevant RFCs (apart from RFC822, RFC2822 and the ones that followed) seem to be RFC3598 which was later obsoleted by RFC5233 and none of them seem to say what should happen if the delimiter is there multiple times...
Neither 3598 nor 5233 is relevant except in the context of a Sieve implementation. Since Postfix does not include a Sieve implementation, they do not apply at all to how Postfix handles subaddress syntax.
