Did you not read the Verizon order? The order that very clearly demands a daily dump of all metadata (source/destination phone numbers, date/time, etc.) for all customers, even those calls wholly within the US?
IANAL but it seems clear that cell site data could be included (since it's held to be transactional data), but it would be limited to the towers connected to when making and ending calls, not a complete timeline. [2]

The question in my mind is what is the purpose for the order. If it is to compel Verizon to do something they don't want to do, then maybe it wouldn't, but if it is to give Verizon cover for what they want to do anyway, then it very well might.
