It's still an annoying process. As someone who didn't itemize but had some weird tax situations (PhD student) it was always a pain.

Also even if you have a drop dead simple tax situation, it's still navigating and filling out a form that reads like the worst spaghetti code. "Go to line 31 on form XYZ". Even if it cost people 30 minutes, that's still less than just writing a check and putting it in the envelope.
