Comment (by spacedmonkey):

 I spent some time testing the PR. It has a net posative result on
 performance. Tested on
 Single / Multisite, 2016, with and without object caching. Also tested
 with and without translation files present.

 Shaved around 200ms off the page load. Great work @swissspidy.
