Of course. Does anyone thing otherwise?

I.e., can DHCP carry options for proprietary things? Do routing
protocol also support non-standards track usages? Etc.

This document is about an extension to l2tp that solves a real
problem. I'm not sure what the above is getting at. We should drop
this work and do something else that is a better fix to pppoe? Been
there, tried that. pppoe is out there, and is broken. It can't be
fixed without a major overhaul that is not backwards compatable.  I
detect no interest in doing this (some folks tried to have a BOF on
this general topic, but there really wasn't consensus/interest to do
this).

So, I view the above as interesting commentary, but largely orthogonal
to whether this document should go forward.
