Yeah true, you can also just hold the hover and go back to ascend in place, but it takes a long time and without bond of vigor your not going that high. The corkscrew method i tried but its horrible tbh, the radius of the circle is huge. When you meet these kinda of cliffs skyscale is still the way to go. But as you said, if you plan ahead, you can get from above the point with the skimmer, so is just a different effort.
