Comment (by gziolo):

 It's excellent to see progress on this front. It'll further enhance the
 developer experience when interacting with HTML API.

 I also want to emphasize the more significant impact on WordPress core
 when this functionality gets introduced. In practical terms, it means that
 eventually, we will be able to read on the server
 [https://developer.wordpress.org/block-editor/reference-guides/block-api
 /block-attributes/#attribute-source sourced block attributes] from HTML
 saved for blocks. This would be a huge win for all the use cases where
 developers want to [https://github.com/WordPress/gutenberg/issues/49437
 consume blocks as structured data]. The hope is that when all the
 development concludes, then when rendering the block on the server, the
 developer will have access to the value of every attribute inside
 `render_callback` through the `$attributes` param. Additionally, two long-
 standing tickets would be simple to implement:

 - Expose block data directly through REST API endpoints (#53603). When
 retrieving a post via the REST API you could get the block data as part of
 the content object instead of the HTML.
 - Expand `get_post`'s `$filter` parameter to allow block data as a return
 shape (#53602).
