As useless mail headers do make emails heavier, I am in favour of

Or if not completely removed, then at least shortened by substituting
to “b=invalided” or “b=invalidated-on-host-A.B”.  The latter is more
useful than just having an invalid dkim-signature. (or removing the
b=/bh= tags and putting instead a new tag containing the host where
the signature was broken, which not really an Authenticated Receiver
Chain, and does make the massage shorter).

See my last post on this.

My mail software has been pruning useless headers since the 80s when we began to import RFC822 mail. It has grown tremendously ever since and its gotten worst.

The idea of "Who cares?" that RFC5322 meta-header waste is widely acceptable, is part of the problem.

RFC5322 Header Pruning SHOULD be a new common practice to be evaluated.

Among others, DKIM-Signature is certainly a prune candidate once validation has taken place a the MDA, i.e. transports have ended.
