This can't be entirely true, can it? The compiler depends on icu4x and that was still building even before unicode-org/icu4x#3060 got fixed. The [u8] hack and unicode-org/icu4x#2834 were sufficient for that (in fact either one should be sufficient). Looks like only some configurations of icu4x are affected by unicode-org/icu4x#3060, and some other configurations are helped by this hack?

ICU4X is many components, the compiler only uses one of them, which doesn't do extremely fancy zero-copy stuff (it only does normal zero-copy stuff).

Okay, so there are cases where these hacks actually help the build to succeed.
@nnethercote can you adjust the comment? Then r=me.

Thanks for the clarification. That makes me feel better about the whole lint :)

Yeah, some cases, though in some cases the last field is a ZeroSlice or something, so I don't think a full ICU4X build is fixed by this. However like I said we have a dep update that fixes this so it's not a huge deal.
