My source: I review a lot of contracts. It's very common for things to be explicitly required.

Yes you can go back and forth and argue the toss, but it pushes up the cost of the sale and forces your customer to navigate a significant amount of bureaucracy to get a contract agreed. Or you could just run AV like they asked you to...
