Yes it is irrelevant.   Now that we have competent risk managers making the decision, they will know how to effectively hedge these deals.   Furthermore, pricing is always available on demand.   When each trader has 30-40 products to manage in a volatile market, they are not necessarily going to put 03-10 for peak and off-peak in every region.

It becomes very cumbersome to manage the year over year spreads when the front is moving so violently.
