Sort of. The infectious disease experts I know and worked with this past year are less worried about a political point and more worried that the immunity fades.
They must not think or read very deeply into their own field then, because there exists the phenomenom of immunological memory, ie the effect where memory B/T cells lay dormant in the body for decades, and upon exposure to the characteristic antigen of SARS-2 (in this case) they ramp up antibody production exponentially. This results in - theoretically, but this is definitely what happens - lower peak viral load, lower symptomacity, and thus lower transmission and a shorter disease course.
Thus even when full immunity to reinfection is gone - which btw the estimates I’ve seen are that IgG lasts a few years before the individual is seronegative again - there will still be immunological memory which persists indefinitely and vastly reduces mortality and morbidity.
