OK, I can see that - I was focused on my own needs, the TCLASS, and that
was very simple to make sticky, no interaction with any other facilities.

But - do you have any opinions on the other issue I raised - the
transition issue?  I will probably have to hack a solution within my
project - there I need packages right here and now (such as quagga and
iputils) that are run-time independent on whether the kernel contains your
patch or not - and to me that says, "use a /proc entry to detect the
semantics".  If I could design and test that solution so other people
might use it, everyone would profit.
