The COCKPIT-1238 epic currently has our notes from the Berlin sprint discussions about service workers. Spend max. 5 days on learning about them, and validating our assumptions.

Start with "Do service workers have access to the TLS client certificate?", as if that is "no", we can bury this idea right away. If "yes", make a demo and discuss if the benefits are big enough to consider the "price" of restrictions in sandboxed iframes/private windows.
