Taking a STRICTLY devil's advocate position here:

Isn't it the case that the thing that knows what the <homenet> label is,
should be able to masquerade on behalf of anything that isn't aware of the
divergence of the three possible values for <homenet>? If you end up with
some boxes thinking it is ".home", some ".homenet", and some
"", as long as one of them knows about all three, it should be
possible to resolve the differences.

The scope of the namespace is "the home network", and never reaches the
real DNS (roots), so at worst it would be folding the three fake namespaces
into a unified (three-headed) fake namespace.

I.e. avoid it if you can, but if you can't, I think the issues are
solvable, even if they get a little funky/ugly under the hood.

None of that should be visible to users, I don't think.


P.S. Guide to implementers - never expose multiple handles for the same
object; over-exuberant users may be tempted to try to "clean up" the
