Our terminology on this needs a bit of cleanup, but the relevant distinction
here is "maintenance". This means that, for example, a security
vulnerability in the package will be fixed, and this is backed up by a
commitment from Canonical (which has dedicated resources to this

We do need to do a better job of both communicating our maintenance
practices and ensuring that they meet expectations. There is work in
progress to change this for 8.04 LTS.

This seems sensible to me; Debian-style components are unwieldy to work
with, as they are closely tied to the way the archive is published. We
should be able to change a declaration of maintenance without moving files
around on a web server, and the placement of the files isn't a very good way
of communicating this information.

This is tricky. In order to be effective, this needs to be communicated all
the way from apt-cache up through gnome-app-install in a reasonably

Sounds elegant enough, though I wonder about automatically granting upload
privileges based on a new dependency.
