Nothing prevents a backend from overriding the method to provide an
optimized version (in fact, I already do this in back-art for some gsc
methods). The NSGraphicsContext implementation would only be a default
fallback implementation for backends that don't want to implement it
themselves.

In this case, it could be done faster in GSGState, but I don't think
performance of arct will be an issue, so I see no reason not to put it
in NSGraphicsContext.
