The tricky part about subscriptions is the indirection between the offer
for the subscription and the content covered by the subscription.  For
example, if "Bob's Burgers Season 1" is available on Netflix streaming, is
Bob's Burgers the itemOffered or is it the subscription?

I'm not immediately getting why we need anything new/special for bundles.
 Why isn't it just multiple itemOffered values?  (or just naming the bundle
itself as the itemOffered.)

Dependent properties (like 'about' and 'aboutRelationship') only work if
they're unique... can we really say 'about' will always be unique?
