+1 to this.
As a short term solution, just removing religion civics from Westminster Abbey would be good. It is very odd and immersion breaking that the final Hungarian UHV is shortcut by a rush to WA to adopt Religious Tolerance in the 1300s.
I'd say all the wonders that currently give free civic access should be changed to boost specific civics or just give general bonuses. So WA can give +1

per city under Divine Monarchy, Magna Carta +1

per city under Feudal Monarchy, move Golden Bull back to Paper (make it the 1356 one) and give it +1

per city under Constitutional Monarchy, Imperial Diet +5 to state expansion stability. At least as a short term measure, until we can find better bonuses for them.
