Done.

This seems overly specific documentation, but perhaps I'm not familiar with
terminology. It would seem that "Blimp Assigner" refers to your
"AssignmentSource", which seems like a comment layering violation (talking about
who uses this, rather than how to use it), but perhaps that's another layer.

It may help to rephrase this comment to explain what the class does, not how
it's meant to be used.

Done.
