Even if a "perfect architecture" existed such that "real machines" are "perfect subsets" (real architectures are very different, sometimes in very weird ways), one of the problems writing a kernel is that real hardware is as buggy (or more!) as the next software (in the end, it is algorithms implemented in silicon, with the added burden that bugs can rarely patched and the rebuilt package distributed to the users).
