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?
