I think there's a good point to Python 3 put-downs (if I take put-down
to mean generally reasonable criticism, which is what I've read here
recently, and not trolling).  And that is simply to register
dissent.

Any online group is an opportunity to register dissent in a way that
is public, open, immediate, interactive, and will (probably) be
preserved for historians to check.  The fact is, some people have
gripes with Python 3; they are letting it be known.  If no one did,
there could be no later time at which people could look back and know
what the reaction was to its introduction--it would just be a blank.
Aren't opinions that dissent from the prevailing ones important to
register, whether one thinks they are right or wrong?
