Is this bitstream work aiming at "current generation" VP8 (think minor, 
but incompatible, bitstream revision - e.g. for consistent motion vector 
clamping and loop-filter ordering suitable for parallel processing) or 
is it aiming at "the next thing" (VP8.1 or VP8+ or VP9 or whatever)?

This mostly boils down to a "will current VP8 content be decodable with 
future decoders" question. Somehow I got the impression from the mailing 
list you are considering breaking the current bitstream before things 
are really widespread and personally I think this may work out okay - 
but you'd have to announce things really really soon. Then again the 
current bitstream doesn't look fundamentally broken, so you might want 
the next breakage to occur only with VP8.1 with additional efficiency
