Yes. But it's still a lot of work to identify what to click on in an overly complicated function / class and then to select "Transmogrification # 17" on it/them.

Getting to a deeper understanding of what the old code is doing takes a lot of work. When we get to that point, refactoring to make what we learned apparent is a good idea. Assuming there is a way to test the changes. (Now I get to spend 2 days making "mocks" in environment X -- learning the mockup tool, and determining the content appropriate for the use cases)

It's a good point you bring up, but it's not a freebie. I am in favor of doing what you said, when you can.
