I'm am beginning to wish for the days at which, at least in
principle, we could standardize something and immediately put a
"not recommended" label on it.   I agree with John and Dave that
having an agreed-upon specification for how to do these things
if one insists on doing them would be a good idea.   I'm just
concerned about the implication of encouragement to do it, at
least without much stronger Security and Operational
considerations material than is now present (and, Dave, that
isn't a vague "don't like it" complaint -- it is a reference to
my earlier note, Keith's notes, ekr's notes, etc.).
