This suggestion is no different from environemnt activation scripts of 
anaconda/pyenv/virtualenv -- without the other benefits of virtualenv.

IPython solves this by creating version-specific executables (even in 
Windows). I see no reason why executables of Python proper cannot do the 
same. In fact, the reason why Windows version went Py instead of this 
seems to rather be to solve a completely different problem -- the 
filetype association (when running a script via ShellExecute, it 
autodetects which Python version to invoke).
