Why the revolution USA and Mexico still exist?They should be replaced

I have a suggestion thread here for an Australian revolution to replace the US →

There were early French and Dutch explorers in Australia at the same time as the British, so I think it would be cool to have it as an option for all three civs (to replace the US). In fact you could even make an admittedly tenuous case that the Portuguese could also work with an Australian revolution :stuck_out_tongue:
