It’s one of those things you either use constantly or not at all. Activating the feature intentionally and having it fail is irritating, but activating it unintentionally because you didn’t know it was there could have serious consequences. I mean, I can even come up with cases where the wrong information being C&P’d accidentally into the wrong Web form could result in someone ending up dead.

Given the difference in stakes, “off by default” makes sense for this feature. I wouldn’t call it a dumpster fire, though—more like a relic of a more innocent time.
