I think I would prefer to call this Web / Hybrid or something like that. The way it's written now somewhat implies to me it's only hybrid but maybe that's just me. Also, I would not use "Mozilla SimplePush URL" since you could, and for a while, would likely have your own SimplePush server. Eventually, we hopefully would have to add entries for Mozilla Network, Chrome Network, etc.…  but until then it will likely be our server to allow cross-browser web push.
