It'd be great, but I think it won't be too easy to implement. I'm almost sure there's another bug in the AbuseFilter workboard asking for the same thing, and hopefully with some more discussion, but unfortunately I cannot find it right now.

I could finally find it :-) I'm keeping this task open because it's fresh. Still, I find this pretty hard to implement. Probably, we'll also want some limitations applied, too. For instance, it wouldn't be good to restore an edit which was disallowed months ago: a feature like this will make users save revisions using other people's accounts. At the very least, I think we should limit it to edits disallowed in the last 24 hours, and maybe add this as a sub-feature of Special:AbuseFilter/revert. Either a new subpage, or add checkboxes to listed edits so that people could choose if they also want to restore the edit itself for the selected entries (in addition to e.g. unblock the user). We should also take some precautions, like to avoid re-triggering abuse filters and properly fail if there's an edit conflict.
