As I understand it, the "Precognitive" badge can no longer be earned for Music: Practice and Theory. I suggest to move it to the "Retired" list.
Followed the Area 51 proposal for this site before it entered the commitment phase
The problem here is that all Stack Exchange sites share the same list of badges, and the badge itself isn't retired (like Tumbleweed is for instance); they continue to be awarded on the newest sites. Customizable badge lists aren't implemented, not even for Meta sites so I doubt your proposal will ever be implemented, but who knows?
