But the "systems" do not know about one another...

Only the integrator knows what "systems" are in its application.

All a single system can say: I want some callbacks
registered -- in the following partial order (among my callbacks).

There may be ordering restrictions with the callbacks of
other (unknown) "systems". That depends on what my and the other callback do.
