My only minor concern is if we should be explicitly disallowing
the 10-bit address prefix.  Isn't that a legal address for 7-bit
systems, however unlikely it is that someone would use it?

If I'm wrong, just tell me.  :-)
If I'm right, it seems like there should be a diagnostic warning
message if someone tries to access a device at that address.  It's
not like the devices move around (at least not in any system I've
played with).
