Ha, I was back-and-forth on editing a response to my own comment with a caveat - there are indeed times when I've found UI editing to be more efficient. There are probably a lot of factors that go into it, but the main one I've noticed is when there are a lot of concrete values that are both numerous and difficult to know ahead of time.

An extreme example is a squiggly line in SVG. Click on a canvas and drag, super easy. Or try typing it out and discover your inner masochist.

So, I definitely see your perspective, thanks for sharing your thoughts!
