Some smarts could be added to pflash to check if hostboot supports xz 
compressed skiboot or not
when you attempt to flash an xz compressed file to PAYLOAD, but that'd 
involve a) some way to look
at hostboot in flash and check whether it has support or not and b) 
adding smarts to pflash, which
probably isn't a thing that should happen.

It would be really nice to know if it works without trial and error, though.
