Comment (by Bernhard Reiter):

 One thing to consider when implementing this is that it somewhat muddles
 the invariant that only the `hooked_block_types` filter can change
 ''which'' hooked blocks are slated for insertion, whereas the
 `hooked_block` (and `hooked_block_{$hooked_block_type}`) filter cannot --
 the latter have so far only been able to modify a given hooked block's
 attributes, inner blocks, etc.

 This might be okay. We just need to be mindful of correctly setting
 `ignoredHookedBlocks` if `hooked_block` or
 `hooked_block_{$hooked_block_type}` returns `null`.
