https://gerrit.wikimedia.org/r/#/c/56545/ (commit to mediawiki/tools/release) set it so E3Experiments and LastModified were not included in future branches (i.e. 1.22wmf1).

However, it was not removed from extensions-list (until just now):

https://gerrit.wikimedia.org/r/#/c/57687/

In between, this caused downtime on 1.22wmf1 sites which TimStarling had to help me resolve.

So make sure to remove any extensions from both these places simultaneously.

I added this to a revised https://wikitech.wikimedia.org/wiki/How_to_deploy_code#Add_new_extension_to_extension-list_and_default.confmake-wmf-branch/default.conf. Please edit away with some info on what happens if you forget to remove.
