Yes. That used to require difficult decision making: “Can I do this and how long will it take?” was a significant cognitive load and source of stress. This was especially true when it became clear something was going to take days not hours, having expended a lot of effort already.

Even more frustrating was having to implement hacks due to time constraints when I knew a couple more hours would obviate that need.

Now I know within a couple of minutes if something is feasible or not and decision fatigue is much lower.
