I thought that Enhances is merely the converse of Suggests, and that it was invented for situations where it is problematic or inconvenient to use Suggests directly, as when a main package wishes to suggest a non-free package. In which case, of course, if "foo Depends: foo-data", then "foo-data Enhances: foo" is already implied. What you're suggesting is that Enhances take on a new meaning: "package has no functionality, so should only be installed as a dependency". But that meaning is really boolean, it does not require a target package. The dependency graph already knows the target package. Since it *is* just a boolean, I'd rather see just a package tag. If one didn't already exist, I would have suggested 'special::useless'.
