OP specifically mentions "cross-vendor" transferable. Which, to my understanding, is currently true.

  You can set up a Yubikey on a mac and use it on a Windows machine. It’s cross-vendor transferrable.

    In this case, we're using the term "cross-vendor transferable" to mean that the key material can be exported out of one vendor and imported into another. So if you could export the passkey from Windows Hello and import it into your iCloud Keychain, that would be cross-vendor transferable. Or if you could export the Resident Key out of your Yubikey and import it into Google Password Manager, that would be cross-vendor transferable.

      The horror scenario of the parent post was completely avoidable with “not cross-vendor transferrable” keys as I describe. This “cross-vendor” property is nice but it’s not required to defend against being locked out of one’s stuff.
