 The notes for Python3.x package should not suggest setting a Python3.x as
 the link for the `python` executable, because `python` was historically
 the incompatible Python2.x, and replacing it with Python3.x causes
 problems.

 i.e in the following:
 {{{
 notes "
 To make this the default Python or Python 3 (i.e., the version run by\
 the 'python' or 'python3' commands), run one or both of:

     sudo port select --set python $pythonNoDot
     sudo port select --set python3 $pythonNoDot
 "
 }}}

 The first `sudo port select --set python $pythonNoDot` should be removed.

 I've had to fix this for a couple people who blindly followed the
 recommendation without understanding the consequences.

 Of course this requests follows years of debate on the topic of what
 `python` should be, such as https://peps.python.org/pep-0394/ (2011),
 revisited in https://lwn.net/Articles/780737/ (2019) TL;DR: `python`
 should be deprecated as it causes confusion.
