Everything other than setting up a pitch black tent, cutting a hole in the fabric, and tracing the image flipped upside down projected through the pinhole is a crutch.
Or, alternatively, there are no crutches, and tools improve over time. I don't think a mechanic would be bitching about someone using a monkey wrench over a regular wrench because "but in my day we didn't need no monkey wrenches we just readjusted the thing 20,000 times".
And, again, your lines of what is or is not a crutch is arbitrary, based on the things you can do. You can't MF? AF isn't a crutch. You can MF? Af is a crutch.
You can develop in a dark room? Digital is a crutch. Can't develop film? Digital is not a crutch.
