Let's do a quick check before going down a rabbit hole to see what impact if any stripping references will have
[x] Ensure this will not clash with T126558
JR: this will not be in the current sprint so we're good.
~~ Disable navbox experiment (remove `.navbox`from wgMFRemovableClasses )~~
JR: decided not to do this as it would be an unfair test to test 7 days prior to stripping references with a completely different environment)
[x] Update wgMFRemovableClasses to include .references on beta channel and stable channel of beta cluster
JR: this is now live as of 16th February.
[x] Update wgMFRemovableClasses to exclude .references on beta channel and stable channel of beta cluster
JR: On Monday 22nd will revert the above change.
 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`
JR: Will measure Fri 27th Feb (5 days of data before and after)
 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).
JR: Can revert on 27th :)
