If multiplexing  becomes a part of HTTP 2.0, as it is likely to be, these will be 'broken' not just in label, but in reality. 

The problem is that they may be deployed and working, but only at the cost of lots of pain and by other implementers (especially intermediaries). I.e., they're only "working" because people have worked around them.

That's your interpretation. The charter doesn't require HTTP 2.0 to accommodate *every* use of HTTP, especially when it's being used -- or extended -- in a non-conformant way.

If we can satisfy these use cases by making some changes to them, that's great, but let's not call it "fixing HTTP."
