One (smaller) suggestion on the PATH situation on Windows:
I noticed that Visual C++ Build Tools installs a number of "Command prompts" under its Start menu item, each of which starts a cmd.exe with appropriate PATH set to the appropriate compiler (32/64 bits or ARM cross-compiler), and assorted environment variables set to the appropriate include/library directories.
Could we do something similar for Python?
I.e., Install under the "Python 3.6" start menu an additional "Python command prompt", which will start cmd.exe with an appropriate PATH so that python and pip run without further prefix.
That way, the installer still doesn't need to mess with global PATH and you can easily have multiple versions of Python, each with their own "Python command prompt" submenu.
At least for Windows users this would simplify the situation a bit.

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).

You can't. Windows versions don't create versioned executables. Got bitten with this myself.
...Maybe they should? (This is python-ideas, after all ;-) )
