I don’t think that needs to be a barrier to implementing the proposed feature request. All the observer needs to do is withdraw their original ID and type a new ID rather than using computer vision to suggest it.
One important consideration is that we would expect the frequency of “novice users who choose opt-out of community ID without much understanding of the impact” to be a whole lot higher than the frequency of “users making informed decisions to opt-out of community ID who happen to have used AI to suggest the original identification”. And for the second scenario, those few users can fix that by removing and re-adding the ID.
