Ah, wordplay. You're saying it works? I'm not convinced.
My experience is that it sows distrust in praise.
"You just said something unpleasant to me, so I don't trust the praise you added after is genuine, and now I don't trust the praise you said before is genuine either. I think you added them just to fit the form of a PRP. Maybe that's what you do all the time. So I think you're basically lying to me about the praise, insulting my intelligence and trying to manipulate me by crude emotional bullshit. This makes me angry".
Which is not very useful if you have constructive critical feedback to give, as it is no longer constructive.
In my view, dressing up a shit filling in a sandwich is a form of shallow manipulative wordplay, and for at least some people, it makes them upset and angry, even if they don't show it immediately. Because if it's done often it will make them distrustful. In some sense, they are right to become distrustful.
Most people need to feel some amount of socially rewarding praise and recognition in their working lives.
But if you're often using PRP... you lose the ability to convey praise to them in ways they will experience as actual for real praise.
So I advocate for separating these things out more, and making it known that is intentional.
When there is shit filling to deliver compassionately, work on the meaning itself, not dissonantly trying to simultaneously convey it and hide it, which puts people who notice on permanent alert that your words do not mean what they initially sound like.
