It's an interesting balancing act. I think when most devs look at JSX for the first time they instantly recoil at the rebellion against years and years of "separation of concerns", yet as you say it's a syntax that devs have embraced regardless.

I love Elm and think it or something very close to it should become way more mainstream, but I do find its bracket-heavy DOM syntax off-putting in comparison.

EDIT: That said, I do agree with the leading commas in laying out models as opposed to the trailing. Scanning the models of an Elm file is far faster than, say, a JS file, subjectively at least.
