With maybe a few exceptions that I'm unaware of, all integrated terminals are optional features that can be disabled. I agree that editor-specific run configurations are over the top and bad form, however an integrated terminal is a very useful feature that I use all the time, especially when working with Go.

Edit: And that said, if I'm paying money for a product it better have features that I'm going to need, and if I don't need them it better have a way to disable them.
