I think that 'normative' model should be initially changed to modelS. I do not think that post-modernist approaches necessarily preclude the normative but extends this to include varieties and subtleties.
I think that after some time normative models will be considered as anomalies and not usable in theory and practically. I do such conclusion watching the present values of Y and Z generations (born in the end of last century).
Such a good question and fascinating to consider. Have you read any of Gilles Deleuze and Felix Guattari ("A Thousand Plateaus"). They will give you one hundred reasons to put them down but keep reading. Of course, Michel Foucault ("The History of Madness") argues so eloquently he is worth reading on the subject. He is wrong and he knows he is wrong, but he opens the door to many important lines of questioning. Like no other.
