Well, yes, that's what conservative means. You're using stable distros, with older versions of Python, and it sounds from your original post like you're not interested in using newer versions right now. So... what's the problem exactly?
Python appears to be a playground for features versus a stable, reliable well tested and well thought out language these days.
And as for the standard lib, a lot of the additions e.g. in 3.3 is simply stuff that's been around and proven for years: virtualenv, mock ...
I mean, I respect that you feel that way, but I just don't see the same sort of cause for concern I guess.
Python has an extensive set of comparability tests and the system is quite modular. It also follows the maxim that complex systems that work are built from simple systems that work.
You don't have to use the new features. You don't even need to use Python3. Sounds more like "Damn kids and their loud rock and roll."
Fine example here (there are loads more like this):
