Why are there dependencies that aren't actually dependencies on some packages?

[Jordon Bedwell]

Since when does Brasero or other packages need/require
liblaunchpad-integration-common to work properly, or they will
suddenly fall to the ground and never work again.

I've noticed quite a few packages that require launchpad integration
when they don't actually need or require it, it's fine to have
launchpad integration, it is not fine to label it as a dependency (in
my eyes) when it is not, a recommend sure, a dependency, seriously?
Should the term spam be retooled to also include packages and their
dependencies now?
