I think in general that creating a new subtype of text to solve this
problem is a non-starter. Part of the original problem was that not
enough mailers supported PGP/MIME (or indeed, MIME in general)
sufficiently well. I suspect that using a new subtype will eventually
end up as "PGP/MIME lite" and will similarly not be supported.
Anything that causes the equivalent of
"cat message | gpg --clearsign | mail user(_at_)example(_dot_)com"
to no longer work well is not going to work out in the real world. I
like the original suggestion far better (with or without the x-action:
tag) as it does not preclude the above pipeline.
