Apparently our DNA is literally encoded with lots of viruses, as they've evolved to become utterly harmless to people. Our bodies are loaded with various bacteria and viruses that have evolved a symbiotic relationship to the point where we'd die without them, and they can't live without us.
I seriously doubt they started out that way.

Smallpox (around since about 500 BC or earlier near as we can tel), still had a 35% lethality rate until it was eradicated in the 70’s though an extensive vaccination campaign.
Diseases can be severely lethal far longer than you or human memory can survive.
So that's why malaria is less deadly now? I've seen this said many times with zero backing, and it just really doesn't correlate with the history of disease. The reason we don't deal with the majority of deadly diseases is vaccines, not because they've evolved to become less deadly.
>I think we have a petty good idea by now actually
We have an idea of how well they work on the original covid-19 strain that we saw last year. We don't know how well they will work on actually eradicating the virus.
>I think the risk is small given such a mutation would possibly render the virus much less virulent
Based on what? It's already evolved to evade antibodies produced by infections from the first wave (P1 strain in Manaus specifically is a good example). Those have been mutations in the spike protein, and have made the virus more virulent and deadlier.
