I'm inclined to agree with you there.  And I will speculate that Bald
Eagle also agrees.

For what it's worth, when I implemented the quadratic Bezier sphere
sweep in the Object Collection, I used the name SSWP_BEZIER2_SPLINE to
select that spline type.  So of course I'm biased in favor of the last
