You can choose not to use the React component abstraction at all and just re-call React.render(makeElements(state), el) at the top level each time your app changes (using pure functions to generate the tree). Our plan is also to support pure functions directly for components that don't rely on state. You can also use the component abstraction but choose not to use getInitialState/setState -- but our goals are to provide a component abstraction that is flexible enough to meet people's needs while still being restrictive enough for us to build higher-level optimizations around them.
