I’m going through a list of blocks of a site I’ve inherited and converting them from their current WP 5 format to WP 6 so that I can more fully leverage ACF Gutenberg. However, I have blocks with names like “duotone-text-image-left” and “duotone-text-image-right” that I’m likely to merge. I still need to leave the old blocks in until the staff have time to track down the pages where the blocks are in use and update them.
Therefore, I can convert these blocks and likely just set a preset according to their name, but I want to mark them as “deprecated” so that while existing pages can continue to use these existing blocks, new blocks can NOT be created.
