No, the main thing separating hardware U2F tokens from crypto hardware wallets is that with hardware U2F tokens the key is totally baked into the token and can't be exported, so it will be lost forever if the token is destroyed. Crypto hardware wallets are unique in that they let you export & import the key. Sorry I edited the post that you're replying to a few times with extra details so you may not have read them.
Oh---you mean you can make one key into a clone of another?
