 you write:
As useless mail headers do make emails heavier, I am in favour of
removing DKIM-Signature headers, that are known to be broken, e.g.
because the current host has modified (and resubmitted) the message.

Look at the headers of the mail in your inbox, particularly mail from
large providers, and you'll find megabytes of headers that nobody is
ever likely to look at or use.  This battle was over decades ago.

I heard this stated by you a few times. I never brought into it. It wasn't a problem to be concern about a few decades ago. Now it is. It's junk and its growing. The more it grows the more overhead we have. It makes systems who are suppose to be ignorant about the junk, work harder. It makes your "View Source" more cryptic.

Simply put, for the MDA/MUA it is overhead not required. It can be pruned by the MDA passing it on to a MUA.
