In T279157, we implemented a hidden change tag for tracking edits made with DiscussionTools' new "source mode with tools" that was implemented in T257391.

This task is about deprecating said hidden change tag.

Timing

Work on this task should not happen until we've finalized a deployment date for T276607 has been set.
