What Seth said. We shouldn't add any more "this would be good to filter
on" headers on an ad-hoc basis; we should implement custom header support. 

(IMO, if there were going to be more, List-Id probably wouldn't make the
list anyway - it's a specialised header for a very few people (who would
use it a lot.) )
