Yeah one of the things that has made me hesitant to buy a YubiKey is that there's no way to get an identical pair so I could take one with me and leave one at home, for instance. And as you said, in theory a site could let you register several but that's rarely supported.

Most sites that support Yubikeys (and other hardware authenticators) let you register more than one, for exactly this reason. It’s at least part of the integration guidelines, though not a strict requirement.
It’s just the software codes where you can’t.
