How can it be wasted time if you're able to build context and a mental model of the repo? The whole point is to "rapidly improve at any programming language" right? Sure, you're not going to contribute net new code but you'll be primed and ready to contribute in the future while achieving your original goal. Whether or not this works, I don't know. But dismissing it as worthless is kind of a stretch and offensive. But thanks for your opinion.
