Swift Protocol Oriented Extensions

Trying to get my head around Protocol oriented programming in Swift and how the extensions work and what level of extensibility it can provide.

Have the following code snippet which I ran through Playgrounds

protocol ProtocolA {
    func doSomethingA()
}

protocol ProtocolB {
    func doSomethingB()
}

protocol ProtocolC {
    func doSomethingC()
}

extension ProtocolA {
    func doSomethingA() {
        print("Extension - doSomethingA")
    }
}

extension ProtocolA where Self: ProtocolB {
    func doSomethingA() {
        print("Extension - doSomethingA Self: ProtocolB")
    }
}

extension ProtocolA where Self: ProtocolC {
    func doSomethingA() {
        print("Extension - doSomethingA Self: ProtocolC")
    }
}

extension ProtocolA where Self: ProtocolB, Self: ProtocolC {
    func doSomethingA() {
        print("Extension - doSomethingA Self: ProtocolB, ProtocolC")
    }
}

extension ProtocolB {
    func doSomethingB() {
        print("Extension - doSomethingB")
    }
}

extension ProtocolC {
    func doSomethingC() {
        print("Extension - doSomethingC")
    }
}

class Implementation: ProtocolA, ProtocolB, ProtocolC {
}

let obj = Implementation()

obj.doSomethingA()

What I get printed is:

Extension - doSomethingA Self: ProtocolB, ProtocolC

Is there anyway that I can guarantee all the extensions to run.

Ideally I'd like to get the following output.

Extension - doSomethingA
Extension - doSomethingA Self: ProtocolB
Extension - doSomethingA Self: ProtocolC
Extension - doSomethingA Self: ProtocolB, ProtocolC

I do understand that Swift, will choose the strongest match in terms of it's types, in fact if I don't provide an implementation where ProtocolA matches both ProtocolB and ProtocolC, I would get a compile time error. Is there anyway that I can go around this?

Thanks.
