True. Adding new binaries is, in my experience, more common than
modifying binaries already on the system.
I don't really mean to be arguing for debsums as a security mechanism,
more just commenting on the general question. I'm on the side that thinks
that debsums isn't a horribly useful direction to go for full-blown
intrusion detection, and that for what it's really useful for right now
MD5 remains entirely adequate.
