Design, tooling, relevance != implementation.

And not saying don't think just pointing out that careful handcrafted logic takes almost the same time to implement anyway.

Most problems are such that it's hard to know what really needs to be accounted for initially due to some janky interface or the language not behaving as you expected which can nuke the whole plan.

Writing stuff down can make you more confident about the approach and ironically lead to a dead end because you assumed everything was accounted for.
