My experience is completely opposite though admittedly this may be because
of the specific projects and cities I've worked with.  In all the cases
I've been involved with giving the ISPs layer 2 responsibility led to a
never ending stream of finger pointing.  I'd also say that just because
your TDR doesn't see a reflection does not mean you have a clean path.
