I wonder if this could be called pattern-partial-syncing.php or similar. While it does a slightly different thing to the js file of the same name, it is a little more descriptive.

I wonder if this might be a bit confusing as we don't add pattern as a support option to the block.json of paragraph. We could probably add a comment to the file about why it works this way.

Similar to the other comment, the name pattern might also not be descriptive enough.

This looks more specific to block bindings (previously connections), but it is indeed necessary for the Pattern block.

I think we could add a better description to this, but maybe I can do a follow-up PR that adds some more detail.
