Yes. If you use a password manager like 1password you can print out the recovery slip and write your password on it. Then all of your passkeys will be accessible.
But in general it's a bad idea to have the passkeys just sitting around in text files so the current managers are largely designed around preventing the tech support scammer from instructing grandma to dump the passkeys and email it to them.
Other than that, which is mostly only a benefit for edge cases around partially compromised devices or servers: yeah they're not much different than random unique passwords. Except they have vendor-lock-in.
But because most managers have no UI for doing this, it's impossible to trick someone into doing it.
