I'm fine with byte alignment, but alos thought it would be nice to leave
room for more flags definition without requiring a new data item.  Bits
are cheap in the control plane.  That said, I'm okay with
reducing/eliminating them if that's WG consensus.

Agreed.  Note that the modem controls if a router can do any control via
the Hop Count Data Item P bit.

I'm very interested in such a message, but also like small and focused
function increments from both standards and implementation
perspectives.  My inclination is to move forward with this one and start
thinking and working on the details of such a request message/DI.  What
do you think?
