OpenSSH version 8.2 introduced support for FIDO/U2F hardware authenticators, via the new public key types "ecdsa-sk" and "ed25519-sk".

I currently have SSH authentication set up in combination with gpg subkeys by using my security key in GPG mode. I am wondering if there is any benefit (especially security related) to the native support over the old GPG solution, but could not find any obvious ones.
