I suspect that publishers are marking up their data in these ways because it costs them very little to do so -- certainly less than supporting a separate API -- and they want to provide information for *potential* consumers, not just existing ones. It's an "if we build it they will come" attitude. Anyway, we will document the workarounds for expressing multiple item types from different vocabularies in microdata just in case a publisher with that attitude wants to use microdata.
