But CFR isn't the only decision input: CFR is only relevant when you can easily isolate some groups harder than others, or else unchecked spread in e.g. the low-CFR age group of children will inevitably reach the elderly as well. E.g. people who work in elderly care can be parents as well, making the infection chain required from lowest to highest CFR age groups very short.
BTW, back in February many then-current spread models where extremely optimistic in hindsight (e.g. aerosol spread was virtually ruled out "because if aerosol was a factor, spread would be much faster than observed", they simply didn't know about other spread-slowing factors), we now know that non-blanket spread control is actually harder.
