I really don't see an "immediate need". The worst-case scenario would be an abusive user running a bot on an admin account and going on a deletion spree at a time a steward was not readily available. This is an incredibly unlikely scenario, as the bot would have to be smart enough to unblock itself and remove autoblocks, in addition to having access to an admin account in the first place. Even if this ever did happen, any damage actually done would be temporary, as any admin action is reversible.
There's still history merges. In principle reversible, but in practice I imagine it would take an awful lot of effort if done maliciously.
