In #69405 I will land an approximation of the sound/unsound mode detection to move the roll through.

The "real" fix needs to check:

1. 2.12 language version or 2.11/2.10 language version for opted-in packages (Latter might be ignorable)
2. language version of entry-point library.

This does not need to run on mobile/desktop which can use CFE auto-detection for sound mode
