After The Great If-Let Outage Of 2024, we audited all our code for that if-let/rwlock problem, changed a bunch of code, and immediately added a watchdog for deadlocks. The audit had ~no payoff; the watchdog very definitely did.

I don't know enough about Cloudflare's situation to confidently recommend anything (and I certainly don't know enough to dunk on them, unlike the many Rust experts of this thread) but if I was in their shoes, I'd be a lot less interested in eradicating `unwrap` everywhere and more in making sure than an errant `unwrap` wouldn't produce stable failure modes.

But like, the `unwrap` thing is all programmers here have to latch on to, and there's a psychological self-soothing instinct we all have to seize onto some root cause with a clear fix (or, better yet for dopaminergia, an opportunity to dunk).

A thing I really feel in threads like this is that I'd instinctively have avoided including the detail about an `unwrap` call --- I'd have worded that part more ambiguously --- knowing (because I have a pathological affinity for this community) that this is exactly how HN would react. Maybe ironically, Prince's writing is a little better for not having dodged that bullet.
