Quoting Tejun from the thread Jiri Slaby likely had on mind: "The fact that they may coincide often can be useful as a guideline or whatever but I'm completely against just mushing it together when it isn't correct. This kind of things quickly lead to ambiguous situations where people are not sure about the specific semantics or guarantees of the construct and implement weird voodoo code followed by voodoo fixes. We already had a full round of that with the kernel freezer itself, where people thought that the freezer magically makes PM work properly for a subsystem. Let's please not do that again."
