I wonder whether there's some synergy with the discussion around conditional conformances on [opaque result types](https://forums.swift.org/t/opaque-result-types/15645/). If we go with one of the proposed syntaxes for in-line conditional conformances there, maybe we could also use it to denote conditional default implementations in protocols?
