I don't think that quite works. When trying to understand and clear DISCUSS ballots, I would much rather that changes are unambiguously displayed for everybody to see, rather than being buried in quite complex email threads (or in non-standard places such as GitHub). Of course you are 100% correct that substantive changes need to pass the rough consensus test, at least on the WG list and possibly at Last Call level, under the AD's responsibility. But I don't think that making it harder to post updates after Last Call is a feature. Regards Brian
