Yes, it's very nice that it proofreads (aka resists mutation).
It seems that existing immunity may reduce instances of drawn-out severe covid which are conducive to mutations.
Also it is potentially useful that we could identify those with lingering acute covid and maximize their treatment, and in some cases quarantine them to prevent mutation escape. People in this category are very rare.
