It's one that's worked quite well for the past 70-odd years in the
military community, since even before there was such a thing as email.
If you want to call something with a 70-year track record a "bad
workaround," well, that's on you.

It's not a technical burden. It doesn't involve any change to
technology. This is a policy issue, not a technical issue.
Then you're doing it wrong.

Yes. However, in my experience expecting the whole software ecosystem
to do things the Right Way is folly. Ad-hoc solutions are at least as
common as the Right Thing, and yes, there are mailing infrastructures
that thread on subject lines.

No, it really shouldn't. Leave RFC4880 alone, please, it's not an email
protocol. Put this out in the email RFCs somewhere, like RFC3156.
RFC3156 describes how to use OpenPGP with MIME, but it doesn't actually
define anything about the OpenPGP standard itself.
