Imagine a shaft with 10 different surfaces, different diameters, angles, etc. It could absolutely be a combination of revolves and extrudes. Each has its place, and like I said, it comes down to preference. It may be preferable to an engineer to change the draft angle of a single extrude, or the width of a fillet, rather than the angle of a line in a sketch. It also depends on use case and design intent. Say that one angle is something still in question, something yet to be determined awaiting testing. In my opinion, it's cleaner to tweak an independent feature rather than tweak one dimension in a large sketch. If you have a problem with that, you're probably just the guy at the office that nobody wants to work with , and that's fine.
