If you try to give `python` (as in python.exe the cli command) a suite of subcommands that match rust or go... that means reinventing pip or creating yet another idiosyncratic multi-tool (e.g. bundling pytest and flake8 or nose and ruff, etc) or reinventing Make (a config file with a line of bash per-tool). Don't want any of that.
But python could use a nice set of subcommands for all the cli tools buried in python. It would be a discoverability tool.
