undocumented_unsafe_blocks) #13316Description
What it does
Unsafe attributes have been stabilized (rust-lang/rust#128771, rust-lang/rust#123757), thus it would be nice to have a lint that ensures // SAFETY comments are in place.
Since undocumented_unsafe_blocks covers impls too, perhaps it should also cover this too, although it may be best to possibly split them (but that is a different issue).
See #13317 as well.
