You could certainly disable RSA-based authentication.

But having RSA-based authentication for the host is definitely better than
no authentication... but, yes, I'd much rather see a "Kerberos for everything"
option available for SSH.

The biggest problem for large deployments of SSH is public key harvesting
and distribution.  Kerberos would solve that.
