You will find that Delta have likely been banging on to this (and other) airport operators for years. Unfortunately such conversations are pretty much exclusively about reducing charges. You can find exactly this process going on at London Heathrow at present, where it has been recently announced that a revision to the new runway/terminal plans has saved GBP 2bn. Guess what contributes to such cost reductions. Reduction of redundancy and resilience of course.
It's not even as if this is deliberately done. The electrical installation is offered to the large specialists that do this work as 'Design & Build'. And the bottom bidder gets the job. You try selling resilience to a client strapped for budget.
