I think sales may be more important. Getting an appreciation for how hard it is to get a customer would alter how a lot of engineers think about features. Customer service is honestly easy in comparison.

Agreed, but one huge problem here is that getting a customer often requires more than a checklist of features, but rather a product that solves a customer's problem well.

I agree that sales, support, and engineering should all have rotations. The sales and support give you very different insights into what customers need which help you out with your engineering.
