I believe this issue is very interesting!

Tracking issue: Connecting block attributes and custom fields
WordPress/gutenberg#53300

(From the issue...)
This issue is meant to discuss how to connect block attributes with custom/meta fields. It includes a list of tasks needed for this, and we will share updates about the progress here.

While working on this implementation, we realized that the internal API we were using could be useful for other projects like WordPress/gutenberg#53705. Therefore, we decided to create another issue to keep track of the WordPress/gutenberg#54536, which will be used to connect block attributes and custom fields.

Block Bindings API: Internal API to connect block attributes and different sources. Not only used for custom fields but for other projects like WordPress/gutenberg#53705.
Custom Fields: Using the Block Bindings API, support for the "meta_fields" source to connect block attributes and custom fields.
