typo: woker

notifyClientsOfControllerChange() is also called from activate() for example. How does the server know the client's new controlling worker if you use ShouldNotifyServiceWorkerConnection::No here?

The spec says to call "Handle Service Worker Client Unload". Where do you do this?

I see, it is used for that purpose as well.
I think SWServer should set it in StorageProcess without having to wait for WebProcess to set it on its client.

In the line just after, when removing client from registration.

Sure, but I do not think it is done currently so the patch would regress things.

Actually, client unload should do these too:
If registration’s uninstalling flag is set, invoke Try Clear Registration with registration.
If registration is not null, invoke Try Activate with registration.

I think a comment pointing the which part of which algorithm is implemented would be helpful here.
