It would also make edit warring easier which is why I'd rather have local wikis hand these out (and revoke for abuse if need be) so they can be give to responsible users who don't edit war. Also, someone pointed out a while back that any vandal who knows what they're doing can easily defeat the usefulness of rollback alone. Image attacks, multiple accounts/IPs, etc can all make rollback useless, and you need sysop tools to deal with the vandals who know what they're doing. It's pointless.
