Because it's much harder to do better design, so often over technological soft good things fall through the cracks.

Like, why aren't more big projects use accessibility as hot reloading if those are so great?

Or, a simple illustration to your reliability point - part of the reason the files are hard to read is because XML is an atrocious format. And also tools like VS aren't even smart to preserve user formatting, so you can't even manually make it easier to read. Why hasn't it been changed in so many years?
