Ehh, nature, she always drags some series into the mix - the mortality rate is a function of distribution across age and other health factors - it doesn't seem to drive the immune system bonkers, so WHO is calling out higher risks to older people, esp those with additional factors such as cardiac or pulmonary impairment. Probably due to the fact this is fundamentally a respiratory issue. Abstractly, more data always helps in spite of the cost to get it, but for us in the USA, the last official action has been to delete the tests_administered count from daily CDC reporting. So that makes any projection more guesswork than not.
