This is useful so methods can do something like this:

> nsresult ChangeURI(nsIURI* aURI, nsIURI** changedURI) {
>    return NS_MutateURI(uri)
>             .SetRef(NS_LITERAL_CSTRING("test"));
>             .Finalize(changedURI);
>}

Bug 1425318 - Allow calling NS_MutateURI.Finalize(nsIURI**)

https://reviewboard.mozilla.org/r/207648/#review213920

::: netwerk/base/nsIURIMutator.idl:319
(Diff revision 2)
> +    NS_ENSURE_SUCCESS(mStatus, mStatus);
> +    nsCOMPtr<nsIURI> uri;
> +    mStatus = mMutator->Finalize(getter_AddRefs(uri));
> +    nsCOMPtr<C> result = do_QueryInterface(uri, &mStatus);
> +    result.forget(aURI);
> +    return mStatus;

some blank lines for better readability would be good, something like:

nsresult Finalize(C** aURI)
{
    NS_ENSURE_SUCCESS(mStatus, mStatus);

    nsCOMPtr<nsIURI> uri;
    mStatus = mMutator->Finalize(getter_AddRefs(uri));

    nsCOMPtr<C> result = do_QueryInterface(uri, &mStatus);
    result.forget(aURI);

    return mStatus;
}

::: netwerk/test/gtest/TestStandardURL.cpp
(Diff revision 2)
> -         .SetScheme(NS_LITERAL_CSTRING("https"))
> -         .Finalize(url);
> -  ASSERT_EQ(rv, NS_OK);
> -  ASSERT_EQ(url->GetSpec(out), NS_OK);
> -  ASSERT_TRUE(out == NS_LITERAL_CSTRING("https://mozilla.org/path?query#ref"));
> -}

honestly, I would leave this in.  it's not bad to test both apis, you never know when the upper level one goes away leaving this untested
