Catalina should be supported for two more years:

Ah excuse me for that. 2 years of additional lifespan is still painfully short for a deprecated OS. Even free OSes like Ubuntu LTS get more years of support than versions of macOS (Ubuntu LTS release cycle of 2 years minus 5 years of support = 3 years of additional support after deprecation).
