The main reason why is that then you can't just blow away the OS 
install pool and reinstall from scratch without needing to do 
something with the data.  For example, you might want to install 
another OS for which there is no current upgrade path.  With zfs on a 
pool separate from rpool, then you could install a different 
OpenIndiana, Linux with ZFS, FreeBSD, OmniOS, Tribblix, etc., and just 
import the existing data pool.  You could also multi-boot the system 
with different OSs which support ZFS and each could import your data 
pool.
