Please! That would be fantastic

And now the latest example: https://phabricator.wikimedia.org/p/Vvjjkkii/ - Wrecked several thousand tickets, before they were disabled on 20180630.

At least now the bot is working on reverting (T198552), although it'd be faster if the bot didn't have to wait on the new rate-limits like users do.

What are we missing here? (snuff?)

Probably Comments are OK? Since https://secure.phabricator.com/D8945

Maybe the current issue is with who can use batch edits?

@valerio.bozzolan: What is still missing is covered by this tasks' subtasks (which often are non-public because WP:BEANS).

("snuff" in this case is basically "normal standards" - https://en.wiktionary.org/wiki/up_to_snuff)
