I think this needs to be split into multiple PRs.

• One that deprecates the Gin* methods.
• One that removes the Gin* methods (after one release).
• One that has the heavy breaking change of changing the method signatures.

Agreed. Actually, I'm also hesitating whether to give users some transition time.

The deprecations give you that. For signature renames, you can't really do it.
