Actually those idiosyncracies are React, not JSX. Using JSX with Mithril I've had no trouble using reserved words as attribute names. Dynamically inserted html in Mithril/JSX is just {m.trust(str)}

Edit: I should also mention that Mithril comes with routing built in, as well as XHR utility and streams. I'm finding streams super useful for sophisticated state management.
