While I hope what you are suggesting is the case, “scientists say it is too early to draw firm conclusions” (from linked article). We just don’t know yet what the repercussions of the most recent infections are.

It seems like a pretty big gamble to not be cautious. Masking, vaccines, and avoiding indoor crowds in poorly ventilated spaces seems to be helpful. Probably best to at a minimum continue to do that until we have more concrete evidence.
