The angle needing to be used as a length (to be able to use the same scale as a unit radius) is something that naturally happens in a lot of trig algorithms.

It depends whether you care more about the "UI" (the user of the algorithm gets a more pleasant input range to use) vs how convoluted the implementation is (somewhere deep down an extra multiply by 0.15915 was needed).

All I am saying that "turns" are not universally better, they have downsides too.
