I know that but the discussion here has not been clear. I responded to
what I thought I heard, maybe I heard wrong.

For a particular IdP and SP to successfully use artifact, one of them
needs an HTTP-Artifact endpoint in metadata while the other needs an
ArtifactResolutionService endpoint. The two are complementary.

Since there are no HTTP-Artifact endpoints in IdP metadata, that use
case is nonexistent, yet that's exactly the use case I "heard" ScottK
describe (so I must have heard incorrectly).
