I never said it doesn't matter. I said it matters. What I'm saying is the scenario you're portraying literally cannot play out pretty much by definition (and also empirically, from what I've seen) unless you accept that code readability for juniors is secondary to program quality. When you make readability your primary concern, it comes at the cost of fixing certain bugs and design issues... precisely because the best solutions may not t be trivial or easy to understand by the junior folks 100% of the time. So you never get into your purported state where everything was well designed and implemented in the first place and now you have to worry about getting a junior to fix a bug. Everything ends up clunky from the get-go and you never get a high-quality, robust program at all. Just something of mediocre quality with a ton of patches from devs of all level to get something like 85% working, shipping with know issues you could've avoided if you hadn't artificially restricted yourself and tied your hands behind your back for the sake of the juniors.
