One can make a panic wrapper type if they cared: It's what the stdlib Mutex currently does:
MutexGuard checks if its panicking during drop using `std::thread::panicking()`, and if so, sets a bool on the Mutex. The next acquirer checks for that bool & knows state may be corrupted. No need to bake this into the Mutex itself.
My point is that "blindly continuing" is not a great default if you "don't care". If you continue, then you first have to be aware that a multithreaded program can and will continue after a panic in the first place (most people don't think about panics at all), and you also have to know the state of the data after every possible panic, if any. Overall, you have to be quite careful if you want to continue properly, without risking downstream bugs.
The design with a verbose ".lock().unwrap()" and no easy opt-out is unfortunate, but conceptually, I see poisoning as a perfectly acceptable default for people who don't spend all their time musing over panics and their possible causes and effects.
