I think you could look at it that way, counting the devs as part of the system. But if you do that, they become the weakness. Attack the devs that fix the bugs & take down the system.
Devs are the white blood cells, fixing the system when it needs fixing, but there is nothing antifragile about that.
The system doesn't become stronger by itself. It literally needs devs to fix the bugs, or the system would die.
