Comment (by bgamari):

 While cleaning up things for the 8.0 release I noticed a TODO in
 `Data.Version` mentioning this ticket. My read of this discussion is that
 the original plan was to remove `versionTags` (at least from the `Eq`
 instance, if not the field itself) in GHC 7.12 (now 8.0). This has not yet
 happened. It would be nice to have some guidance from the Core Libraries
 Committee regarding what is slated to happen on this front in this
 release.
