Not sure how you avoid reinventing any of the component frameworks. Writing custom JS component backbone style seems tedious and error prone. Manually modifying the DOM on changes means writing the same logic several times, once for the initial render and then repeated in every event handler that has change the state of the UI. Alternatively, you might just be nuking your DOM with inner html and then running everything again through the initial rendering logic. But this isn't ideal, components loose focus, there can be glitches, and it can get slow. Not sure how you could make the type of complex UI heavy apps and have any greater flexibility or faster maintenance.
