Why would users choose to do that?  Using "python" presumably already works for them, so what benefit do they get?  If the main advantage is they can now use shebang lines, then the specific options the script wants can be expressed in that line.

I use "py" interactively rather than "python" because I have 2.7 and 3.2 installed, and py -2 or py -3 gives me the explicit version I want without PATH hacking.

If 2.7 and 3.x provided python2 and python3 executables explicitly I might not do this (I'm not at my PC right now so I can't recall if 3.x provides python3.exe as well as python.exe, there was talk of this certainly, but 2.7 definitely doesn't include python2.exe).

Having said that, I don't use other command line options much, so the limitation doesn't bother me much (py -3 -m xxx would be the most likely usage I'd miss...)

If the extra options really mattered to me, I could probably hack up a Powershell alias easily enough, but py -V is available and does 99% of what I need.
