I don't get how the removal of Largest Acknowledged would work.  We use that as an anchor point for the ACK frame, but without it you need to start at 0.  Then you need to allow the first range (or gap, depending on where you want to start) be zero-length.  It's not really that simple.

This smells a lot like a v2 issue to me.
