I think people just have to let go of the sense that these numbers are anything other than a snapshot in time. It's not like something gets written down in a book somewhere that the great Covid-19 of 2020 had a case fatality rate of 3.4 / 5.7 / whatever. It's just a ratio between a numerator and a denominator, and both of those numbers are changing at different rates as time passes, as testing increases, as containment practices change, etc.
