&gt; Seems like a perfectly fine thing to do to restore service during an outage, as long as they&#x27;re rolled back or reviewed later.<p>Rolling back later seems to forgotten in most cases (unless it&#x27;s disabling a feature). Then you end up with this weird behavior and code path that few remember. &quot;Oh yeah we did that when....&quot; You usually only rediscover it after that quick hack is a problem. This is decades of experience here.
