I personally agree with this in the big scheme of things. Computed attribute names seem overkill and I worry about adding logic to JSX. But, honestly, I could care less if they were added if such features get other people all fired up.

My personal taste though often does wish for object shorthand and dropping curlies. My sense off the top of my head is that the majority of my actual props look something like `<Widget user={user} id={id} timestamp={timestamp} />` since I mostly avoid setting up data inside JSX. Is it a big deal? Of course not. But it would be nicer to just write `<Widget user id timestamp />` or `<Widget $user $id $timestamp />` or whatever syntactic sorcery would be settled on.

A modest advantage of dropping curlies is it reduces the already tiny force of one argument for styling in CSS over JS: "prettier and less typing". I certainly don't think they should be dropped just for this reason of course, but could be a side effect worth noting.
