Some introspection capabilities already exist because they are intrinsic to the hypervisor. There are a number of additional capabilities that can probably be implemented with minimal changes to the hypervisor. And as you say, other capabilities may indeed require more lines of code or incur performance penalties such that they are not deemed worthwhile. This is of course a question of fundamental tradeoffs. However, the benefits of introspection are too great to ignore. Also note that other hypervisors are working on introspection projects and Xen may have to follow suit if only to be competitive.
