I have read and support this draft.  Admittedly the prose is probably more
difficult to read than necessary (which might have prevented more people
from reading it, but also, August is a time when a lot of people are on
vacation), but the draft describes an idea that seems important for
scalability.  So I support it progressing, and apologize for being late on
this last call.

Random very-unthought-through thought...Suppose half the RBridges did no
pruning on, say, half the FGLs...and the other half of the RBridges pruned
on those FGLs, and did no pruning on the complementary set of FGLs?  Could
this somehow reduce table size by 50%, and make filtering happen just one
hop later than if all RBridges filtered on all the FGLs they needed to
filter on?
