Personally, I don't think it's likely that anything will get committed
here without someone doing more legwork than I've seen on the thread
so far. I don't have any plan to pick up this patch anyway, but if I
were thinking about it, I would abandon the idea unless I were
prepared to go test a bunch of stuff myself. I agree with the core
idea of this work, but not with the idea that the bar is as low as "if
it can't lose relative to today, it's good enough."
Of course, another committer may see it differently.
