That's a straw-man retort. I never said every task requires one to go up a mountain. I only said that sometimes a software developer has reason to stop and think.

Also I would suggest that ad-hoc analyses and other such hacks are unlikely to lead to PRs and other visible artifacts.

I should have been more clear; I was mainly disagreeing with your first sentence. The rest mostly makes sense to me. Ad-hoc analysis was only one example, you could easily replace it with working on a prototype, where part of your goal is to find mistakes by making them, as that is often the most efficient way to discover what the problems with your design are.
