[Note that this had been the "polite version" of what I actually think 
about your proposal.]

"The GNU standards" is a standard of its own, predating the FHS.

Number #1 reason: /usr is ment to contains non-essential packages, only, 
and thus is allowed not to be present during certain stages of booting.

In theory, yes. However /etc still needs to be mountable rw: (To set up

be mountable "rw:" (Consider ROMs, CDROMs, etc.)
