Now that I see your change written out, I don’t see any downside to this.

> Source/WebCore/bindings/scripts/CodeGeneratorJS.pm:1144
> +    $result .= "    return result;\n";

We want WTFMove(result) here, otherwise we end up copying the result to make the Optional<> version. Saves work and reference count churn when there are data members that have non-trivial constructors.

> Source/WebCore/dom/ClipboardEvent.h:37
>      struct Init : public EventInit {

No need for the "public" here.

> Source/WebCore/dom/CustomEvent.h:44
>      struct Init : public EventInit {

No need for the "public" here.

> Source/WebCore/dom/EventModifierInit.h:32
>  struct EventModifierInit : public UIEventInit {

No need for the "public" here.

> Source/WebCore/editing/Editor.cpp:884
>      RefPtr<DataTransfer> dataTransfer = DataTransfer::createForCopyAndPaste(policy);

This should be auto.

> Source/WebCore/editing/Editor.cpp:889
> +    init.clipboardData = dataTransfer.get();

This should just be standard assignment. I don’t think a call to .get() would be needed here; RefPtr = RefPtr should compile and RefPtr = Ref should also compile with no get call.

Well, the downside is that we'll have to pass non-nullable wrapper type as raw pointers for now. Thankfully, this is not common in dictionaries (only 1 instance in WebKit).
