I agree. An expired resumptionToken is just the same as a resumptionToken
that was never valid. Hence 400.

To be helpful to harvester writers/operators (especially if you opt for
such a short life for resumptionTokens) you could include text content
with the 400 response that says that the resumptionToken has expired.
