Comment (by peterwilsoncc):

 > Standardization happens after `pre_get_posts` but any modifications on
 the SQL clauses' filters will not be standardized by core and will need to
 be handled by plugins.

 This was incorrect, trunk has a few additional items standardized prior to
 `pre_get_posts` that doesn't exist in 6.7 or earlier.
 [https://github.com/WordPress/wordpress-develop/pull/8685 PR#8685] moves
 the new standardization until after the hook fires.

 Items that had existing standardization are not modified, if it happened
 prior to `pre_get_posts` in 6.7 the behavior is retained.

 There are changes for the form of `$query` passed to the SQL clauses but I
 think that's acceptable as they are very low level filters that require
 care when implementing.
