Big reason for this is that most “FOSS” teams are hard-core keyboard navigation nerds (no offense intended, we know who we are), and so, their preferences are completely different from what normal computer users want, so even with access to source and unlimited free time, there is a high probability that a pull request would be shut down because the maintainers don’t want or don’t understand why spacing between elements is 8pt (“2px is just as functional as I want it”) and why keyboard autocorrect should be off for that text field (“what is autocorrect? Never heard of it”).
