I live and work in London and many people I know with professional jobs including myself didn't go to school in the UK. We don't understand why most children in this country do at least 7 GCSEs with the majority do 8 or 9.
As far as I know there is no minimum requirement other than English and Maths which is totally understandable.
There is this thing called Ebacc with 5 subjects which sounds sensible to me.
Why don't schools just do Ebacc and spend the rest of the time for non examined activities, be it creative, sports, community, home economics, whatever they like? They could still have all league table requirements such as Progress 8, Attainment 8, etc and etc.
