Looking through https://jakearchibald.github.io/isserviceworkerready/ it seems a lot of features have support that matches what's on https://caniuse.com/#feat=serviceworkers . I'd suggest using numbered notes to point out any areas where support should be partial and what subfeatures are missing.

Here are what i think is missing

1. Debugging support
2. Background Sync
3. Caches
4. Post message doc needs to be updated to inform about service worker limitations
5. Split fetch into fetch-request and fetch-response or update to mention opera limitations

Here the open tickets

1. Caches API - Add Cache Storage API / Cache API #3122
2. Background sync -
   1. Add Background Sync #2677
   2. browser coverage for service worker background-sync #3837

How do you handle sub features ??
