Thread:Translation UX feedback/"Add description" confuses users

People are adding edit summaries in the place for message documentation, perhaps because there's no other place where they can explain something (45831?) or perhaps because the button is confusing.

Example: [//meta.wikimedia.org/w/index.php?title=Translations%3AFree_knowledge_based_on_Creative_Commons_licenses%2FPage_display_title%2Fqqq&diff=5383860&oldid=5383859], but I've seen several others. I bet this is now the vast majority of qqq edits on Meta, but I can't see it easily because we have no CleanChanges there.
