That's basically how it works for complex aircraft. The 777 was the first airliner to receive automatic EASA approval after FAA acceptance.
Smaller nations follow FAA or EASA. Russia and China have their own certification systems but defer largely to the Big Two for imports. However it is notable that the Chinese regulator took a long time and much persuading before they accepted the Max.
Why it isn't done at an international level I don't know. Small aircraft could still be certificated nationally if they're not intended for export.
