Well, I think you still need to answer questions like

* Is it a fingerprint of the cert or the key?

* Is the server expected to re-normalize the DER?    Allowed to
  re-normalize the DER?

So that the input to the hash is well specified.
Several protocols within the IETF have taken on the challenge of
describing how to fingerprint certificates.  I think the document would
be improved by picking one of these strategies.
