#127907, though it wasn't noted in the crater run.

though it wasn't noted in the crater run.

Because the regression here is only for doc builds. The crate already doesn't build on stable. I don't know if you already noticed this, but it sure threw me for a loop.

This crate has been deprecated by them (see their issue https://togithub.com/unicode-org/icu4x/issues/4302).

Would it make sense to retire it from our crater runs either?
