Comment (by prettyboymp):

 After some further digging, I noticed that the
 `WP_REST_Server::get_target_hints_for_link()`, which attempts to match
 internal links to handlers also degrades quite a bit as new route handlers
 are added.

 The default `/wp-json/wp/v2/posts` endpoint ends up calling running this
 for every post returned in the collection.
