It also seems to me that it was a perfectly appropriate question
for this list.  The question was "why did you developers drop this
(obscure) feature that we depend on in Python3?"  I don't think that
question would make sense on python-list.  Granted, there's a fuzzy
line there, but pylint is really development infrastructure :)

The python-porting list would have been a good alternate choice.
