I disagree. The more senior you are, the easier it is to generate something and be convinced that "ok, this is good enough" or "aight, I see these things that need to be changed instantly". Frankly, compared to others, I don't have that much experience (about 10+ish years), but it saves quite a lot of time for me.

It takes a bit time to build intuition around the workflow, but when you get going, it seems surprisingly useful. I was a skeptic before as well, btw.
