What was exactly duplicated? You created unspecific, lose binding...

Why this is RFC? RFC means we should not review.

No, it does not work like that. Compatibles are fixed, not fluid. It's
quite a hint that your merging is wrong approach.

Previous bindings has only 2. Your patch is difficult to review and
understand.

All of these are reset controllers? I doubt.

All of these have children? No, sorry, but this merging does not make
any sense.
