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.
