Please not that in the Debian case, nothing depends on python-is-python3.
It is only provided so that users can manually install it if they have
a Python script not provided by Debian that requires it.
And note that Debian also provides a python-is-python2 package, and
obviously things would eventually fail if packages actually were to
depend on either as this would open up for conflicts.
Thus all Python scripts in packages provided by Debian are required to
explicitly specify either python2 or python3 on the shebang line.
