Immunity after getting COVID should fulfill vaccine requirements

You can’t “demonstrate immunity”. You can test yes/no for the presence of antibodies, which does not guarantee immunity. There exist quantitative tests of how many antibodies you have, which give a lot more information, but as best as I can tell, they aren’t used outside of clinical trials – I know my immune-compromised SIL has been trying to get a quantitative test and her doctors just looked at her funny, so she’s given up.

Either they can track it or they can’t and that applies to all the vaccines.
