I think it is in the nature of the PKI. Most other PKIs know a priori
where to find the certificate store, or they are provided with the cert
chain with a request.

"Enterprise" applications are probably just know. For S/MIME, HTTPS and
most other internet applications provide the cert chain.

I don't believe that many other PKIs have the need to retrieve all of
the published objects, starting just from TA material.

I have echoes of a conversation with Steve Kent or Russ Housley playing
in my head, but the closest I can come to a quote is that we appear to
have one of the few useful applications of SIA. So I suspect that it
just hasn't come up before.

I think that the TA material in our profile appears to be (1) through
(4) that we inherit from 3280, (5) that we get from 3779, and in this
profile we should probably add a (6) for the URL.... Which will be the
SIA, if the TA is provided as a self-signed cert.

Alternatively, if there isn't a URL in the TA material, where do we
start pulling pulling certs from?
