I think Python 3 should be preferred if the user prefers it.  And if
the python interpreter invoked by "python" is not the preferred
version, then how can Emacs know which one is the preferred version?

If macOS needs special treatment, here, we can install a change
specific to macOS.  But let's not skew all the platforms because of
macOS.
