Thanks! Pre Approving, but we need :

• changelog update
• docs update and maybe release notes and migration document (explaining that apps should add a new method).

I think #13497 already added that.

I think #13497 already added that.

It doesn't in a right way. Changelog should be updated, stating that the new Interface is introduced. Moreover we should add docs / release notes stating why app should add a new implementation.
