I think the issue here is that python users seem less likely (per user
on average) to edit the related Org-mode support (i.e., ob-python.el)
than users of some other languages which may be less popular in the
large but have better Org-mode support.

Also, as a maintainer of Org-mode's code block support, I personally do
not use Python.

Best,
