Hello!

Nice. I recall there was a lot of sentiment against this back
when - in particular from Alexey. I cant remember the details

Indeed, I refused to do this.

Sometimes, we have to determine that an address is local in a context
where we do not have information to form a proper request to rule database.
In this case we do direct lookup in fixed table, which is designated
to contain local routes. So that rule 0 was hardwired to lookup in the
same table.

Frankly, it will work provided we do not require too much of self-consistency.
Those days I could not stand this, but it is not illegal.

Alexey
