My point is that it's totally idiotic to start talking about new
kernel interfaces, when strace doesn't even use the ones we HAVE, and
have had for a long time.

So the strace use is clearly not a valid reason to start worrying
about new interfaces. It doesn't even care about all the improvements
we've done several years ago.
