While not what I'd do for every site, it's a pretty neat tool for some use cases. In particular, Heroku has moved to a similar setup with Boomerang [1] - a JS include that puts the nice Heroku branding at the top of your add-on configuration pages. It neatly sidesteps the need to make a component/template for every single framework and backend in use by their different partners. I could also see it being useful as an easy "drop in" way of tying the branding+nav together on a number of different sites within an organization (so your auto generated docs, your tutorials, etc all live on different systems but easily look the same). 1 - https://github.com/heroku/boomerang https://github.com/heroku/boomerang
