This may be true, but at least x509 will get you certificates right out the gate (sadly without reliably working reject lists).
I've yet to get to the point of moving to "modern ssh" (ed25519 key/certs, chacha20-poly1305 encryption etc) - with certificate only. Because keys are *so' convenient. But they're also, while better than passwords, pretty bad: No expiry, no easy rotation, no easy revocation.
I will say this though: it should be quite feasible to move to modern ssh, banning keys and passwords (other than perhaps as a second factor), and moving to certs only. But clearly deployment of reasonable ssh setups are lacking behind the technological improvements.
