I think Alexander is arguing that we shouldn't revert 27bc1772fc & dd1f6b0c17
in 17. I already didn't think that was an option, because I didn't like the
added interfaces, but now am even more certain, given how broken dd1f6b0c17
seems to be:

I think we should apply Alexander's proposed revert and then separately
discuss what we should do about 041b96802ef.

I think it's a bit hard to propose something concrete until we've decided
whether we'll revert 27bc1772fc & dd1f6b0c17.
