[RJ] I am inline with these points.
I would like to confirm a point here... Reclaiming the turnon-8138 flag in
MOP>=7 would mean that 8138 is _mandatorily_ supported in the nodes above
MOP>=7 such that they no more depend on this flag. This in itself is a
bigger decision! Is my understanding correct? While the advantages of 8138
are obvious in non-storing MOP case, they are less impacting/obvious in
storing MOP case.
