Yes. It is interesting that this approach is also the correct
approach for a pet name system to use with TLS. In the TLS case we
have an entranched business model, that results in poorer security,
and prevents this use of a certificate chain. (Because CAs will not
issue certificates to keys which can be used to sign other
certificates, an organization can't have a single signing key
certified by a CA and then sign separate machine keys for each of
their servers.)
