 I'd like to be able to access and if needed modify the parsed blocks for a
 page before it's rendered on the frontend. My particular use case invovles
 ensuring pages have a certain structure with some exceptions that can't
 reliably be address by simply using hasBlockType or filtering an
 individual block's data.

 My current solution is to hook into the `block_parser_class` filter and
 return my own extension that simply filters the ouptut of
 `WP_Block_Parser:parse()`. It works great but it's a bit of a round-about
 way.

 I think for sanity/caching friendliness it should be added in the return
 logic of `parse_blocks()`.
