Future of service worker tooling

[jeffposnick]

I know that there's a decent number of folks who follow the issues here, so I wanted to provide a link to some of the team's thinking about the next-generation of service worker libraries: GoogleChrome/workbox#61

We don't have any current plans to end support for sw-toolbox (or sw-precache, for that matter), and we know there are a significant number of web applications that depend on its continued functionality.

But that issue outlines our general thinking about a rearchitecture of the libraries, along with some snippets of code, and is what we expect much of our new development efforts to focus on.

Would you be open to me adding a short, but consistent message on both sw-precache and sw-toolbox calling out that we're working on the next version of the libraries over in sw-helpers?

Fwiw, React don't currently do this in their main repo for Fiber support (https://github.com/facebook/react/) but given we're moving work to another repo there may be value in doing so.
