A big question that I don't see addressed in the text or asked here yet: why does this require the user to not be in private browsing mode? Some necessary API that's not available in incognito mode? Is the restriction temporary?

Empirically service workers don't seem to work in private browsing mode, and the demo relies on running Dendrite as a service worker.

> In Firefox, Service Worker APIs are also hidden and cannot be used when the user is in private browsing mode.

Doesn't any difference then become a way for websites to detect if you're in incognito, which is something browsers have been fighting back and forth every version?

I'm not a web dev, but I'd guess this is because the implementation relies on browser storage, which is removed when a private browsing session ends. So possibly it would work, but only until the tab / window was closed?
