> Those who have previously had an infection with mild to no symptoms should be acknlowedged as a third group in evaluating public health policies (vaccinated, previously infected, and unknown exposure).

Do we know that this is something not currently taken into account? I wouldn't be too surprised if this is already influencing policies. The other thing is if it's being communicated to the public. Also, the data the officials have is most definitely a lower bound since not everyone with COVID was captured by the statistics. Add all that nuance and it may be difficult to send the point across in a way that is understandable to everyone...
