Yup, that. Vote with your keyboards. Apple writes software with the same tools and languages - if they considered this stuff a problem, they'd have fixed it by now. Besides, Apple has mechanisms for feedback, and it's not open letters on GitHub.
It's not good but it's workable. Which Apple accepts as a reason to focus very few resources on dev tools.
Yes, this letter should probably reference a bug#, but it should not be in the bug itself. And, because it's an open letter, you can go add a bug and make a PR to add it to the letter.
