But it's a huge convenience for running multiple Python versions, particularly as no existing Python versions install executables with the version in the name (python3.exe, python3.2.exe, etc).

Perhaps this could be changed? As far as I can see, python.exe is a small executable around ~25KB (all the code being in the DLL), so there doesn't seem to be any harm to make a copy of it named either pythonXY.exe or pythonX.Y.exe.

Antoine.
