FWIW, a very strong +1.

IMO, we should be specifying thing to work in the best way
possible.  I suspect we could probably do a better job of
explaining decisions and the tradeoffs that went into them so as
to reduce the odds that good people will make bad decisions in
the hope of avoiding the evildoers.  Explaining particular
decisions will probably serve us better, at least with those who
want to Do the Right Thing than taking positions that are too
easily interpreted as "because we said so".
