Comment 5 for bug 11381

(let's use this bug to represent all of the similar issues with packages in the
base and desktop seeds)

I talked with Colin about this a while ago, and in the course of the discussion
I considered that using Recommends may be appropriate. They have the semantics
we want: install this package by default if the user hasn't seen it before, but
allow it to be uninstalled if they later decide they don't want it.

The major obstacle (as with other uses of Recommends) is that different apt
frontends handle them differently, due to there being no support for Recommends
in apt proper.
