I am always wondering whether to use Identifier or const Identifier& in such cases.
I have difficulties keeping it consistent. Since it is a Variant, it is better to pass it by ref?

space between ] and ( is apparently our style.

auto& here and in other various places below ?

This may end up topOrigin to be destroyed on the main thread. Shouldn't we isolate it?
Ditto below probably.

> +    }

You can probably write it as:
auto registrations = WTF::map(WTFMove(registrations), [this] (auto&& registrationData) {
    return ServiceWorkerRegistration::getOrCreate(*scriptExecutionContext(), *this, WTFMove(registrationData));
});

> Source/WebCore/workers/service/ServiceWorkerContainer.cpp:545
> +    m_pendingGetRegistrationsRequests.clear();

I would try to use one map that keeps DeferredPromise instead of typed DOMPromiseDeferred.

> Source/WebKit/WebProcess/Storage/WebSWClientConnection.cpp:140
> +    ASSERT(isMainThread());

We do not do that often when receiving IPC messages.
Should we try to do that more aggressively? Or should these assertions be moved to the lambdas instead?

I am not sure in the case of a Variant so I figured better safe than sorry.

Uh? ok.

ok.

Will isolateCopy().

Ok, wasn't familiar with WTF::map()

Will look into this.

No need for this variable and refing topOrigin probably as well.
