The idea is to create a new plugin type called "Admin tools" that would help to organise the stuff in /admin/ directory.

What is the difference from "local" plugins? It would be tools intended for administrators. Local would be still "all the other stuff" mostly without admin UI.
What is the difference from "admin reports"? Admin reports could be deprecated.

Benefits?

• language pack cleanup
• it could encourage contribs
• core tools could be removed/disabled/replaced
• we would not need to put core stuff to /local/ such as local/qeupgradehelper/

Potential problems:

• adding of current tools to admin tree in the correct order - this could be solved with weights or 'insertbefore' or simply alphabetical order

(I do not remember it now exactly but I supposed this was originally proposed by David)
