If you install a package which has scripts and you don't write versioned scripts, a second installation of that package (with a different Python version) will cause the first script to be overwritten. Much of the time this won't matter, but there might be scenarios where it does.

Speaking of which, it's worth describing exactly what we had to do for ensurepip. That has 3 configurations:

POSIX system default: pip3, pip3.4
Windows & venv default: pip, pip3, pip3.4
Alt install: pip3.4

There's currently an issue where "make altinstall && make install" is slightly broken, as it won't add the missing "pip3" command.

So consider me in the school that suggests this be a standard installer feature that can be applied to any entry point script, rather than something that varies by project.
