Finally! I wish OpenSSH also plan making RSA optional at build time, and set a timeline for removal shifted 1 or 2 years after DSA.

We are also likely to start exploring a post-quantum signature algorithm soon and are mindful of the overall size and complexity of the key/signature code.

That's great news, if OpenSSH contributors commit to adding post-quantum cryptography, it's bigger news than DSA removal.

The problem seems to be finding a post-quantum algorithm that doesn't get obliterated by pre-quantum computers like what happened to SIKE:
