json-mobx - Like React, but for Data (Part 2)

This is a follow-on to MobX - Like React, but for Data, in which I noted the parallels between MobX and React.

• A computed "renders" a "view" of some data, and automatically updates when the source data changes. Like a React component, except generalised to cover any data, not just Virtual DOM.
• An observable is like the setState facility in stateful React components, except that its automatic ability to notify computed (and autorun) observers works by spooky "action at a distance" and so doesn't have to take place inside one component.

But this still leaves one major feature of React unaddressed, and that is reconciliation. What is this about, and how can it be useful in a more general way in MobX?
