Which in all cases results in processing the junk queries locally.

You bring .local into existance for sites that are not using
.local.
The existing uses of AS112 don't bring zones into existance.
They just *replicate* existing zones for local processing.

No, I am not telling them that. If I said "run your own root"
I would be telling them that.

With the contents that they have copied from an authoritative
source. "local **** COPY ***** of the root zone"

They can add entries today without having their own copy of the
root zone. Having a local copy of the root does not change that.
zone tld {
type stub;
masters { ....; };
file "tld.stub";
};

Creating a ".local" changes the response. It also restricts
future changes.

That happens today. There are ISP's which feel the need
to use a alternate root. Do you think they actually edit
the local root zone or do they transfer it?
