We could add staleness markers, e.g. if data is regularly arriving, add a marker after expected interval * 2... But this won't work for all metrics. Consider a scheme like geras_allowstale: as a prefix when querying?
Alternatively maybe this is inferring too much about the data we should force users to work this out via range queries and/or timestamp().
