I would be all in favour of renaming the former Polytechnics back into Polytechnics.
Then it would be clearer that if you want to improve your employment prospects in some specific way you go to a Poly, and if you want to be an academic you go to a Uni.
But both would still be able to offer degree level qualifications.
If the only people going to uni were gonna be academics there would be about 3 people going to uni
