Objectroot: a new filesystem hierarchy for Unix-like systems

This is an interesting direction, but highly underspecified.

There are many edge cases not addressed (eg. creating a user named "common" would probably be bad), and inconsistencies (eg. software from the PSF going under /org/python/, which is probably also where would you expect PyPy to be found, even though it is a different organization).

What does this reformulation have to offer over Plan 9's union mounts, which let me create arbitrary hierarchies to my own specifications instead of following someone's arbitrary "standard"?

It's unfortunate for the people designing / promoting this, not to mention NixOS as previous work.
