yes, some leakage will occur.  and many UAs and MTAs will mung these in 
such a way that it becomes impossible to reply to such messages.

of course.  after all, it's this very set of interoperability isssues
that makes ACE solutions so compelling.

I suspect you're confusing quoted-printable with RFC 2047 and its
predecessors.

but if one is going to "review" the experience from that decision,
(which I agree is relevant, and we've already done some of that)
then one also needs to compare it with the experience of just-send-8.
