Reasons for feature removals are not translatable #123920
Description
Code
#![feature(box_syntax)] fn main() {}Current output
error[E0557]: feature has been removed --> foo.rs:1:12 | 1 | #![feature(box_syntax)] | ^^^^^^^^^^ feature has been removed | = note: replaced with `#[rustc_box]` error: aborting due to 1 previous error For more information about this error, try `rustc --explain E0557`.Desired output
The note ("replaced with #[rustc_box]") should be translatable, rather than hard-coded in compiler/rustc_feature/src/removed.rs.
Rationale and extra context
The reason field in RemovedFeature cannot simply be replaced with a DiagMessage because rustc_features cannot depend on rustc_errors (cyclic dependency). I don't know how to solve this.
