because that is just a workaround caused by unexpected behavior?

because it would need to be implemented in all unit-files across 
distributions including user-overrides?

because restart of services with requires is not that funny anyways

because it should not be needed and is *only one* sample case while the 
problem is a greater one where your idea don't scale at all

come on and solve the call below that way while at boot and shutdown 
they all get started/stoppe din right order automatically!
