Improve custom blocks registration

[pierre-dekode]

Just an idea!

Core just landed (in 6.1) a copy:block-json Grunt task to:

Introduce a new Grunt task (copy:block-json) that scans and converts core block.json files to PHP arrays and stores them in a single blocks-json.php at build time.
Use the new blocks-json.php file in the register_block_type_from_metadata() function.
Assign the block registration data to a static variable (cache) so that it’s only loaded once per request.

My understanding from that comment is that it's not yet available for custom blocks — only for core blocks.

But maybe we could have a similar build task in project base to get the same performance boost and limit unnecessary file loading.

This is really interesting @pierre-dekode. WP 6.7 introduces wp_register_block_metadata_collection() for bulk registering a collection of blocks from a manifest file. Let's implement this in T2 for WP 6.7+

Can you open a issue in T2 for this and close this issue seeing as there are no blocks in Project Base?
