A plan that spells out every line of code to change gives you no leverage: it costs as long to read as the pull request, so you end up skimming it and reading the code twice.

And the plan doc, what was bad about it is it didn't give you leverage. The plan was every single line of code that was going to change like in diff blocks and like all the new stuff to write. And so like people would review these plans. We recommended this. We told people to read the plans. We read all our plans. And then eventually I found myself like I just kind of skimmed the plans.
