Urm, no good reason, though I did want to just have to type one
passphrase once when Dom0 boots and then be able to create and resize
partitions on top of the crypted one without bothering with any LUKs
stuff...

Also although I have been using LUKs for a while I'm not so experienced
with LVM or Xen so it's been a learning curve and I didn't think of
doing it the way you have suggested... ;-)
