This definitely works until you hit one of a few cases I can think of:

* Adding animations to elements. By blowing away the DOM and inserting new elements each time, you'll trigger any css `animation` for new elements entering.

* Stale data. If your template isn't re-run when some data changes for whatever reason, you'll continue to render the old data. You've got to manage the lifecycle of state updates yourself.

* To counter that, you might just re-run your templates when _anything_ changes. This works until you have a significant amount of data, then performance starts to become an issue.

This won't come up for many cases though, so for simpler apps it's definitely more than enough!
