I think this pattern is also useful for creating tightly performing middleware. However it needs language, compiler and library support to really take off wrt large scale adoption. Ie, when someone marks gives a `Resource` annotation to a struct, then the compiler also generates a `ResourceHandle` and a `ResourceManager` for you which does all this work. All the internal SoA (structure of arrays work) is handled for you as long as you implement the `ResourceFinalizer` interface (for non trivial resources)
