Note here that the useSource API will likely change during this release cycle. So we should probably wait to address this until that is done.

Having said that, I started this branch as an experiment to see how it could work. It's on my to-do list to review it and open an experimental PR at some point.

@SantosGuillamot How much time do you think that will take?

Hopefully it isn't something that will end up being merged very close to the 6.6 beta, I'd rather see these changes made early, and pattern overrides can even help inform the implementation.

Editing the value of the sources, which is what is needed for this use case, it's planned to be the top priority of block bindings for 6.6: link. And to do that, the API must meet the requirements for pattern overrides.

I can't say how much time it will take to be ready, but I feel confident that it will be available earlier in the release process.

@SantosGuillamot Is there an update on the status of useSource? Let me know if there's anything I can help with reviewing.

We've spent some time to understand better the different use cases and requirements for useSource to ensure that whatever we build works for the different sources, including pattern/overrides. I feel we have a better picture right now. I'm working on reorganizing the block bindings project on GitHub, and it's clearer how to approach it after that.
