Sortof. In practice, I have 2 "live" yubikeys per purpose, since I want a USB-A and USB-C set depending on whether my computer is plugged in to the hub on my desk or mobile.

That gives me redundancy in case I accidentally dropped one in a blender or whatever. But also for anything high-criticality (basically anything where losing both yubikeys would lock me out permanently without further backups), I have another yubikey sitting physically-secured. It works out nice, since that's the same approach I was taking w/ "security question" answers and other recovery tokens.
