I don't agree with this. I mean, UE renderer is the subject of countless hours of effort and optimization. But for instance the startup time (or build time for that matter) of a UE game is quite long and it is fairly easy to beat in a bespoke engine. That's one of the reasons looser coupling would be great. I would love to be able to use the UE renderer in the context of a different engine.
