I would suggest we wait until after LPC to see what Christian's design
is (given that, from what I've heard, it will help us solve more
problems than just the kill(2) issue).

I am very skeptical of adding new procfs files as an "intermediate
solution" (procfs is the most obvious example of an interface which is
effectively written in stone). Especially if this would conflict with
the idea Christian will propose -- as he said, there were proposals to
do this in the past and they didn't get anywhere because of lack of
discussion and brainstorming before posting patches.
