No, because people want to filter:

To be sure it's good (when checking enabled): proto.checksum_good == true

To find those which are bad (when checking enabled): proto.checksum_bad == true

To find those which are good, or not checked: !(proto.checksum_bad == true)

It opens up a way to craft intelligent filters based on the tuning of
individual protocol dissectors.
