As individuals those averages are looking at too large of a group. There are known subgroups with different risk profiles and grouping them together isnt helpful. You get very different risks from both for for example a healthy <30yo male and an obese >60yo male.

We have had that data for a while and simplifications serve no benefit. Its not early 2020 anymore, as always, as we get more accurate data, we get to adapt some strategies based on that.

edit: Not to mention the difference in strains (omicron vs delta) as well as the confidence into the different risks (under counting (detection problem) vs over counting(hospitalized/dying from vs with covid)
