Great question, don't know, right now the most vital thing is that hospitals are not overloaded with dramatic influxes of care-seekers, so whatever helps stem that tide.

My concern is not overwhelming hospitals translates to 20 years of lockdown. It isn't feasible. But we might not figure it out until we've destroyed the economy. Then we end up with the same deaths from the virus we were trying to prevent, plus the suffering/deaths of a crippled nation/economy. This sucks.
