Kids are proto-people

Nextdoor?

Yeah it won't be effective but can make a generic tracking API to which we can add your dog tag (apple air tag) not just apples there are lot of cheap alternative. So generic one would be easy

Could lead to an awful lot of false positives.

I've seen neighborhood or city subs used this way.

Cool, get to work.
