Isn’t this a platform-feature-existence thing, not a WebKit feature toggle? So, HAVE, not ENABLE.

I think we should typedef the uint32_t in our code, and refer to it as a "LayerHostingContextID" everywhere. Otherwise, "contextID" is just too vague, and too easily confused with other types of context.
