Why?

The only things that break are things outside of the official repos,
and the vast majority of the user repository works flawlessly. If I
get something from the source, I normally run it explicitly ("python
the_thing") and on the very rare occasion it breaks (when it's 2.x and
uses "python" to mean "python2") I can trivially patch or wrap it, and
file a bug report.

The python = python3 choice of Arch is not what takes up maintenance
time, and it's good to prepare developers ahead of time. That's what
rolling release is all about: getting the best and preparing the rest.
