Make Pip detect Pip/Python mismatch

On Windows, in a normal Python installation python.exe and pip.exe are not in the same location.
python.exe is directly in [PythonInstallDir]\.
pip.exe is in a subfolder [PythonInstallDir]\Scripts\.

I’m aware of this aspect, but I thought the installer adds both paths to PATH when the option is checked.

Currently pip does tell where it’s installing stuff, so simply reflecting which python it is using and whether the internal python version of pip and the env are the same (in those cases where that info can be easily found), could already be beneficial imo.

But if it isn’t interactive, surely it’s too late at that point? Or at least, waiting for an installation and then uninstalling again is annoying, and then it still has to be redone properly.
