Are you suggesting to have a linestring with anonymous coordinates, but
some of them can be assigned IDs?
Because if you want a proper topology, the way branching off must
somehow reference the "node" instead of just the coordinate, else you
wouldn't know if there's a connection.

No, I'm not prepared to discuss them with you.
