Right, that's making things consistent with pretty much all of our other
--enable-FEATURE flags which default to yes if the needed libraries are
present.

Lua was already behaving like that, so it made sense to make python3 do
the same.

Note that you can always force the value one way or another using
--enable-python or --disable-python.
