We usually add a line between SoftLink headers and others.

> +#include "GPUErrorScopes.h"
If it is a unified build issue, we usually fix this in cpp files, not. h files.

ifier id, bool privateMode, WebCore::MediaPlayerEnums::Preload preload, bool
preservesPitch, bool prepareForRendering, WebCore::LayoutPoint&& layoutPoint,
WebCore::LayoutSize&& layoutSize, float videoContentScale,
CompletionHandler<void(LayerHostingContextID contextId)>&& completionHandler)
Probably do not need to have &&, we could probably pass them by value.

It would be better to call completionHandler even if there is no player.
Maybe contextId should be an Optional<>?
Maybe ASSERT(m_proxies.contains(id));

Forward declare LayerHostingContextID?
> Source/WebKit/Platform/cocoa/LayerHostingContext.h:28
> +#include "LayerTreeContext.h"
Do we need this one?

m_layerHostingContextId does not seem used anywhere.

LayerHostingContext::createPlatformLayerForHostingContext(contextId);
contextId here can be 0, is it ok.
If we are using an ObjectIdentifier, we are sure this will not be 0.

Can we use an ObjectIdentifier<>?

s/auto/auto&/?
