Okay, sounds like using HTTP codes for this causes problems in
practice.

What about returning a different content-type for that case?

200 Ok
Content-Type: application/x-das-error

<body>
Something bad happened.
</body>

Pros:
   - doesn't add a new header
   - just as easy to detect in the client
   - easier to support on the server for some use cases
