This eliminates anonymous devices completely. So I guess you are asking
for a different naming scheme, something like <parent-id>.child#<no>
e.g.? Well, we would end up with fairly long names when a complete
hierarchy is anonymous. What would be the benefit?

I'm really just looking for some simple, temporary workaround without
touching the existing fragile naming scheme. What we really need is full
path addressing, but that without preserving all the legacy.
