Yeah, addings just certificates to the agent requires protocol
extensions to match them against already loaded private keys. It's
messy and complicated in a piece of code that we really don't want
to be messy and complicated.

But you don't actually need to load a certificate into an agent to
use it with an agent! You can just have the private key in the agent
and specify CertificateFile in ~/.ssh/config or on the command-line
and ssh will match the private key to the certificate when it is time
to use it (well, it should anyway).
