Are we reading the same policy?
Debian Policy Manual
Chapter 9 - The Operating System
9.1 Filesystem hierarchy
9.1.1 Filesystem Structure
The location of all installed files and directories must
comply with the Filesystem Hierarchy Standard (FHS) ...
(should 'hierarchy' have a capital, or perhaps 'Structure' not?)
What software writes to /usr ?
If you're refering to 9.1.2 that seems not too far from the FHS.
