If you don't like Google's implementation, you should use another one. It doesn't make much sense to say "I can't do X with my thing, therefore I can't do it with anything".
The fact remains that, if you want a Passkey you can write down, you can do that.

Once more, maybe this is possible in theory. In reality, I can't find any way to use apple's passkey implementation on my android phone.
Maybe in theory. In practice, I couldn't even look at the passkey Google has created on my android phone. So you absolutely cannot write it down.
