What are your security concerns?
I find network-route is too much hassle, so I use network-bridge on
every host. The network setup on dom0 is similar to that of a switch
with upstream trunk connections and multiple vlans. If (security-wise)
you can live with trunks and vlans on switches, you should also be
able to use it on dom0.

Note that you can also add routing/NAT on top of bridge setup, which
makes dom0 networking similar to that of a L3 switch/router.
