Kernel solipsism

x86_64 imposed no significant cost (in terms of run-time performance or code complexity) on the rest of the kernel. Xen adds extra complexity to code used by a large number of people but benefits a significantly smaller number of people. The cost/benefit ratios of the two are almost directly opposite.

You haven't answered the question, Matthew. I wasn't asking about costs (I'm more aware than many on how Xen support impacts kernel complexity).
