A specified app seems quite a likely reason to me. And
if they've gotten used to "python" taking them to python3.x,
they'll get a surprise when it suddenly starts pointing to
2.x after they installed an older Python for what to them
was meant to be a restricted purpose.

I just think the python2 and python3 worlds should be
kept separate by default, seeing as there are both forwards
and backwards incompatibilities.
