PEP 432 is also related, as it includes the "pysystem" proposal [1] (an alternate Python CLI that will default to -Es behaviour, but is otherwise similar to the standard "python" interpreter).

I knew this was being specified somewhere, but I couldn't find it in either the tracker or PEP summary. As an aside Nick, what do you think about splitting the pysystem proposal out of PEP 432? I think they could certainly live as independent PEPs albeit perhaps the pysystem one dependent on 432.

The rest of the discussion though makes me think we may actually need a *nix equivalent of PEP 397 (which describes the "py" launcher we created to get around the limitations of Windows file associations).

Perhaps!

Between that and the interpreter identification mechanism defined for the PEP 425 compatibility tags it should be possible to come up with an upstream solution for 3.4 that the distros can backport to work with earlier versions (similar to the way users can download the Windows launcher directly from https://bitbucket.org/pypa/pylauncher/downloads even though we only started shipping it upstream as part of the Python 3.3 installer)

We're getting pretty close to a real idea here. :)
