I love thoughtful pushback as well as a good rant, so thank you (really). I completely empathize with the use cases you listed. Only thing I'll point out is that I'm only quibbling about the mode of interaction (UI vs text), I'm definitely not advocating that designers or non-devs should know or care about react/webpack/tailwind/blah/blah. Agreed that a nicely integrated design tool would hide all incidental complexity.
