We've added an exception for suppress-post & suppress-topic to make them not go into RecentChanges (https://gerrit.wikimedia.org/r/#/c/111158/)
While it works, I'd prefer to have stuff like this centralized in FlowActions.php so we don't lose track of it.
This is not urgent, just making sure we don't forget about it ;)
