Does it actually matter?  What RFCs say (or don't say) about 240/4 means 
precisely nothing to the deployed, non-field-upgradable CPE that I understand 
is driving the interest draft-weil.

That IMO is the rock that proposals to use Class E have floundered on.
There is a lot of gear out there that will not be able to
deal with any Class E internetworking protocol, little prospect that
that will be changed any time soon, and a general feeling that it is
unwise to spend limited resources changing this.
