This can be made unnecessarily complex, but solving the current problem (of
mixed user and system files in folders) is straightforward:

- Add "My Themes" and "My Plug-Ins" folders to the root folder.*

- Whenever the same theme exists in the user folder and the system folder,
prefer the theme from the user folder.

- Whenever the same plug-in exists in the user folder and the system folder,
prefer the theme from the user folder unless it's older than the plug-in
from the system folder.

Once this is implemented, users who like how it works now can still use WP
that way.

people through WP installations and upgrades that I'm confident that proper
names (i.e. for people) and locations (i.e. not buried) would really help.
