Nice. Would that come with a corresponding update to the pip and setuptools versions in RHSCL such that their wrapper script generators did the right thing? I bring that up, as one of the other challenges with the way SCLs currently work is that the upstream convention of copying "sys.executable" into the shebang to generate a script that runs in the current Python doesn't work as expected.
