If we were writing virt-install again today, we would make it the default, but we've had two Fedora release where virt-install defaulted to sparse files. Changing existing behaviour of a command isn't all that nice, even if there are potential benefits to be had. So we added the --nonsparse flag and left the existing behaviour unchanged.
