My former company used to have engineers sit on sales calls regularly too.

While it was interesting to see what companies wanted and how they were sold our product, it wasn't extremely illuminating.

The features that customers wanted were already on our roadmap, we had one feature that customers found confusing and hard to use, but it was written that way to meet the needs of our largest customer.

Engineering wanted to streamline it but then it wouldn't have met that customer's needs. Eventually we wrote a "lite" version of the feature that was easier to use and turned that on for everyone but the big customer. (but that didn't come about because of engineers sitting on sales calls, we all knew it was hard to use but couldn't change it until it was on our product roadmap.
