Managing needs-packaging bug reports

Are needs-packaging bug reports legitimate bugs? If they are should they be tracked in Launchpad? and against the Ubuntu distribution?

There are a tremendous number of needs-packaging bugs reported in Launchpad and they are currently intermingled in the list of bugs without a package. The value of triaging the needs-packaging bug reports is questionable since they are wishlist items for inclusion in Ubuntu. Should anything be done to separate the needs-packaging bug reports from those without a package and if so what?
