Do we have any data on what people are actually using?

As long as the C11-isms are in MSVC-only code, it seems like this is
exactly equivalent to setting a minimum MSVC version. I don't see
an objection-in-principle there, it's just a practical question of
how far back is reasonable to support MSVC versions. (That's very
distinct from how far back we need the built code to run.)
