I'm actually fine w/ JSX being "dumb" and just translating `class` to `class`, but when used in conjunction w/ React, the end result is that the JSX "markup" has a lot of traps that simply don't exist in similar libraries like Mithril.

`className` isn't the only offender. `onClick` and `readOnly` are other notorious one. And then there's stuff like `xlinkHref`, because it's not like anyone ever imports SVG from external tools.
