Let's do a quick check before going down a rabbit hole to see what impact if any stripping references will have
 Ensure this will not clash with T126558
 Update wgMFRemovableClasses to include .references on beta channel and stable channel of beta cluster
 Use [[ https://gist.github.com/jdlrobson/a358f9ed079fbc9ebf18 | script ]] to measure impact on beta cluster post-change for `webpagetest.enwiki-bc-mobile-beta-2gslow.anonymous.Barack_Obama.us-east-1.Google_Chrome-emulateMobile.firstView` and `webpagetest.enwiki-bc-mobile-2gslow.anonymous.Barack_Obama.us-east-1.Google_Chrome-emulateMobile.firstView`
 Revert both changes after collecting ~~10~~ 5-10 days worth of data (since we don't want to break sauce labs browser tests of the references feature).
