Quite honestly, I am surprised that US model makers have not done this more. Instead we get "Fully" detailed kits with poor detail. Some engines look like total lumps and are for the most part never really seen. Sure you have the satisfaction of having built the engine, but, for what, you can see it most of the time. I never go around opening hoods on my finished builds, most of them are in boxes and are not seen at all. Tamiya has become the standard for kits, like it or not, and even with sparse engine detail, they still looks way better than most kits. But once again, if you don't like it, don't buy it.
