Much like scripting APIs in applications formed the modern figure of pipeline engineers, and later ICE introduced many people who didn't think of themselves as technical to maths and digging yourself out of a hole with your own shovel, I reckon you guys should look at this as an opportunity to step it up a notch instead of being intimidated by it :)
Anything that takes away some entry fee from development tends to show people that they are really capable of a lot more than they gave themselves credit for rather than alienate them in my experience, and I have high hopes CE/Fabric might be another step in that direction. Incidentally, this is also why I routinely whinge at a few selected people about providing more examples, doco and context with their APIs and tools, because 99% of the barrier to entering more "serious" development is that the admission ticket is often exorbitantly high (IE: C++ + OpenGL and viewport plugins), but once you get past that barrier, it tends to be cruisty for a while. Fingers crossed the Fabric guys understand this :)
