Yeah, I had an uneasy feeling when I first saw that the hashcash stuff
was hardcoded into message.el, too.  And it went even uneasier now
that I realised that the draft code also uses scratch message buffers.

It does bind the message hooks to nil when it does this, as does the
resend code.  So I'm wondering if it wouldn't be more appropriate to
resort to using hooks for hashcash.el, which would IMHO result in a
more deterministic behaviour.
