I think this is fine, although:

I am half-tempted to mark the lowercasing of the regex as deprecated (or
at least discouraged). It's such a hack, and I don't think we will ever
improve to make it work in the general case, as regexes are simply too
complex for us to handle all possible inputs.

Either way, though, this is definitely an improvement over what is
there, so:
