@rust-lang/infra could we get a check-only crater run for this?

There's no point in cratering this. Certain old winapi versions that are in use will fail, but they won't be tested on crater.

see #49765 and linked issues/PRs

RalfJung · 2019-06-11T07:23:33Z

Seriously, winapi? 😢

Do you think there is any point in issuing a deprecation warning such that, maybe in a year or two we can remove this accidental feature? (I am still assuming this is an accident -- the feature is incredibly niche, can be easily worked around by factoring the common code into a const, and only works in a very limited set of syntactic contexts.)
