The guardrail should block ONLY when there are zero other active super users. With the previous <= 1 condition, revoking/deleting a superuser was incorrectly blocked when there were exactly 2 superusers total (count of 1 other <= 1 triggered the block). Change to < 1 so that having 1+ other superuser(s) correctly allows the operation. Co-Authored-By: Paperclip <noreply@paperclip.ing>
