Comment (by peterwilsoncc):

 Honestly, the second part was playing around with micro-optimisations to
 see if comparing a string would be faster than type checking.

 The main focus has been avoiding looping through the posts in the first
 section when it's known their complete objects or IDs. I'll get
 [https://github.com/WordPress/wordpress-develop/pull/8495 PR#8495] back in
 a normal (ie, running a full, unhacked test suite).
