On the other hand, that behavior worked correctly on its own terms,
and this behavior seems to be broken, and you've been through a whole
series of possible designs trying to figure out how to fix it, and
it's still not clear that you've got a working solution. I don't know
whether that shows that it is impossible to make this idea work
sensibly, but at the very least it proves that the whole area needed a
lot more thought than it got before this code was committed (a
complaint that I also made at the time, if you recall). "Surprising"
is not great, but it is clearly superior to "broken."
