Expose GeoLocation to workers #745

Regarding the very recent comments following on from: -
https://github.com/w3c/ServiceWorker/issues/745#issuecomment-344128148

Can any of you please explain what is wrong with the complete POC solution
here: -
https://drive.google.com/drive/folders/0B7Rmd3Rn8_hDNW1zSWRoXzBTclU

If the proposed solution is somehow deficient or not fit for purpose please
let me know!

I believe the permissions/user-visibility conundrums to be the only loose
end.

Please also note the plethora of use cases detailed by numerous people over
the years that can be found here: -

I do not understand Marcos' claim that there is little browser interest
when Edge and Chrome are waiting on a specification to implement. Firefox
already allows tracking of users in the background today.
