Comment (by ericmann):

 Patch above created via GitHub does three things:
 1. It adds a 405 header when XML-RPC is disabled.
 1. It adds a 403 header when authentication fails.
 1. It adds whatever error is encoded into `IXR_Error` automatically when
 any other error is throw.

 The last bullet might be unnecessary and is a little outside the scope of
 the original ask, but was a relatively straightforward add to the behavior
 of `IXR_Server::error()` so I threw it in for completeness.
