As a dev I have spoken directly with customers in multiple projects, but based on mentioning revenue/marketing it seems you're coming from a consumer focus and not b2b implementations? It seems to be a common perspective on this site but it's not the only one.

Talking with a customer was great when we could, usually it's been when I worked in a small team (1-3 developers), speaking with either internal or external customers. We talk through what is needed then the BA/PM documents it in the updated job brief, rather than the other way around which leads to so much back and forth. It gets to the root of any uncertainty about what they want much quicker.

This is not any official brand of Agile. It's just our natural inclination when left alone. Talk, iterate, deliver.
