Well yeah; Python 3.0 is just over a year old with 3.1 -- the first robust
3.x release - is about six months old. From the beginning uptake was
expected to take years, not months, so saying that 3.x is not popular enough
seems premature.

No one has said bugfixes will cease.

I never said that I wanted to make this announcement specifically to provoke
outcries. I said if there happened to be outcries we could possibly visit
the issue again. Basically I was being considerate and trying to leave the
door open to discuss things in the future even though I don't see the
situation changing.

No because that suggests new features will be coming to 2.x which is not
going to happen. If you want to say there will be continual bugfix releases
for 2.7 as is par the course for Python and that the number of bugfix
releases might be more than normal then I am okay with that.

That came and went already a couple months ago when we discussed stopping at
2.6 instead of 2.7 (see the various threads at
