Python should've abandoned and deprecated 2 ages ago. I still see new tutorials teaching 2. What the hell.
...and honestly, whats wrong with that?
really, what difference does it make if people use old python versions?
Other than the core python team, which get to be embarrased that many people have zero interest in the work theyre doing?
Does it affect you? nope. Does it break the ecosystem? nope. Does it make library authors suffer? nope (dont support it if you dont want to).
Come on. Live and let be.
If you love python3, use it. Dont winge pointlessly (not you personally; all the hostile frothing at the mouth python3 advocates, especially on reddit)
I guess you can decide for yourself if the 'official support' of python is a massive drain on resources that could be used else where.
(The red line with a few commits now and then is the 2.7 branch)
I really don't know where else you think those resources could have been used that wouldn't have resulted in Python 3. Unless you consider "doing nothing meaningful" to be a form of support.
