A reduced rate of severe cases still is simply a mere constant factor that won't save us. Unless the rate goes down to approx. zero we're back to square one where there is almost no immunity and the number of simultaneous severe cases will easily and quickly rise far beyond the hospital capacity due to the very high rate of infections. On average, there are hospital beds (of any kind) available for about 0,3% of the population. If 5% of the cases are severe enough to require hospitalization, this means that hospitals get completely overwhelmed when 6% of the population are down with COVID simultaneously. And that's assuming that every hospital bed can be used, which is unrealistic.
