This is a theoretically more pure solution because you are trying to break down compatibility to its common factors, the processor, and then do as little work as possible to get it to the point of portability. Less abstraction than other solutions. The holy grail would be a generalised solution for any processor, using nothing but electrical engineering first principles, but I don't know if that's possible and maybe the better solution is to just not have the frankenstein's monster of hardware we have today.
