This warning is produced if you annotate an enum with `@frozen` but build without library evolution enabled. The problem is that if you only build with library evolution enabled for release builds, this leaves you with a warning for all debug builds. The downside of this change is that if you never build with library evolution, you may have this unnecessary annotation without noticing.
