Perhaps you confused "it feels like" (implying that it feels bloated with many esoteric and/or generally useless features) with the statement "there's literally never been a feature that they've said no to" which is something else entirely and what you seem to be disproving here.

In that case, does it really feel like they've said no to any enhancement request that's come through?

From my experience, and those who have watched issues for ten-odd years, I'd say the opposite is true, but I'm not working on a competing product.
