we can really make use of this project (or something similar) at welt.de
one of Germany's biggest daily newspapers. I have been told on GitHub
that, while no new features are being added, the project is being kept running. I am not quite sure what this implies. Our situation is that we have students writing widgets that might be shown on our front page and they should not break anything else on the page by, let's say, doing something like document.body.innerHTML = "";. Since we don't want to have iFrames over iFrames on our site, it seems the only way to deal with this is to check the code, supported by tools like Caja (?). So I am wondering if Caja is suitable for this and if it is still maintained in the way (and feature-complete) that i still can be used for a high-traffic website.
