You mean the logic to avoid painting when there is a page load happening? Don't we also use it for other purposes too? It's unclear to me what we call as layer tree freezing is what we want across all the ports. I suspect there is a subset of things it does like skipping rendering updating steps and/or painting that might be beneficial across ports. If you're talking about extracting it and moving it to WebCore, that does seem reasonable but it would be a lot bigger engineering task then.
