Hop count is a path cost.
You can certainly have more than one default route. If you have one
with a higher cost, it won't be used if the lower cost route is available.
Why would metrics not be used for routing in the kernel? That would
more or less castrate Linux as a an IP router. What changeset did this
happen in?
