I think that the author is speaking about their world, in which they regularly encounter a specific use of trigonometric functions which would be simplified (conceptually and computationally) by skipping the conversion from and into radians.

I think that's a good way to think about software optimization. Deep inside nested loops of a game engine (TFA's example code comes from Godot), that's often what you need to do to squeeze some performance characteristic into your hardware.

I think they are trying to expand it beyond their world. They already have this in their world! Shown with examples. Just want it elsewhere as well.

Not everything is about software automation! Especially in this regard where decade long established practices work on legacy hardware and systems. This is ruining/complicating things for some chip of the scope.
