The fact that we can't use ICU on Windows, though, weakens this
argument a lot. In my experience, we have a lot of Windows users, and
they're not any happier with the operating system collations than
Linux users. Possibly less so.
I feel like this is a very difficult kind of change to judge. If
everyone else feels this is a win, we should go with it, and hopefully
we'll end up better off. I do feel like there are things that could go
wrong, though, between the imperfect documentation, the fact that a
substantial chunk of our users won't be able to use it because they
run Windows, and everybody having to adjust to the behavior change.
