NAT out of the box isn't going to mess with your host's networking to
the point of breaking it. Anything else, like Lennart pointed out, all
bets are off.  A packager has no way of knowing what your network
interfaces look like e.g. do you want a bridge on eth0, eth0, tun0,
wlan0? That and bridged networking entails promiscuous mode as I pointed
out, which may not be suitable for some environments.

NAT is the low hanging fruit and gets a working virtualization stack up
and running with minimal effort on the packager's and user's behalves.
