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
[] Disable navbox experiment (remove `.navbox`from wgMFRemovableClasses )
[] 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).
