That seems reasonable.

But I think another option would be an angle with *zero* points,
where the points are implicitly the corners of the background
positioning area, and which otherwise matches your formula.

If that meets the use cases for angle gradients than I think having
zero points would be simpler than having two.  The question is what
those use cases are, exactly.
