In {T220016} we introduced new schema to track user actions on mobile web. Once new `MobileWebUIActionsTracking` schema gets stable and Analytics department is happy with it, we should remove the old `MobileWebMainMenuClickTracking` schema and all instrumentation code written for it.
Once code is removed, please additionally add a decommision note on the [[ https://meta.wikimedia.org/wiki/Schema:MobileWebMainMenuClickTracking | Schema:MobileWebMainMenuClickTracking ]] meta wiki page.
####Developer notes:
During {T220016} we made a patch to remove all code related to `MobileWebMainMenuClickTracking`, but before train cut we decided to postpone deploying code removal as we decided keep both schemas live for some short period of time. We reverted the change. This ticked is made to solely track revert of revert once Analytics is happy with new schema.
