Yeah, but GPS sync is only going to work if all the 11ghz links are Mimosa (it also makes the B11 even more spectrally inefficient, since you're limited to using a fixed ratio). But my point was that if you want to use an inefficient radio to lock up spectrum, licensing the channels both directions isn't really helpful over just licensing one channel each direction, since whatever you replace the B11 with when it comes time for more capacity almost certainly isn't going to be a half duplex radio.
The B11 has it's place... no other 11ghz radio can move close to a full gig for anywhere near the price as far as I know, but the fact that it eats up so much spectrum does have to be considered.
