Why do you think the virus would all mutate at the same time everywhere? If we let a variant spread, and it mutates in someone there's no system update that will suddenly make the mutation appear in everyone else. It's not a Trojan horse. In reality it would probably just mean that everyone with the earlier less dangerous variant is probably immune or somewhat immune to the new variant if it ever "hops in the opposite direction".
