No, but I am ;) The current out of tree Xen patches are very intrusive because there hasn't been much incentive to reduce their impact. I've going through it all and very carefully rewriting it 1) be cleaner, 2) enable/disable itself at runtime, 3) have clean interfaces and interactions with the rest of the kernel, and 4) address any concerns that others have. In other words, make Xen a first-class kernel citizen. Most of the intrusive stuff has already been merged (and merged for some time now), but without dom0 support its only half done; as it stands people are using mainline Linux for their domUs, but are still limited to patched up (old) kernels for dom0. This is a real problem because all the drivers for interesting new devices are in the new kernels, so there's an additional burden of backporting device support into old kernels.
