This is a pragmatic and arguably Apple-centric decision. But also it's fairly arbitrary, as the Enterprise doesn't have a number pad.

Basic sketch for state snapshots: an extra field on Target.

I think it doesn't make sense for states to own a target as that complicates the concept of Media. Plus they're distinct because it makes sense to have only one per Target. Let's see how this pans out.
