So, one of the items that Margaret suggested was some text in
the node requirements doc or the scoped addr arch that states
that nodes default to being in one site.

However, there has been some mention that people would prefer
different behavior in routers.  That is, the stated desire
was that, by default, each interface on a router be in its own
site.

This suggestion leads to the model where hosts with multiple
interfaces will assume that all its interfaces are in the
same site (e.g. have the same site-local zone id) unless
explicitly configured to have multiple sites.  While routers
will default to having a unique site-local zone id for each
interface (thus rendering SLs to link-local behavior) unless
explicitly configured to have multiple interfaces in the
same site.

This difference in behavior for hosts and routers leads to
some interesting issues.  One big one is how the site-local
zone ids are setup and potentially changed when a host
becomes a router or vice versa.

What are others' opinions on this issue?
