This is probably a reasonable official solution with an opt-out (possibly the recent email-me-about-nearby-meetups option could double as that), but I don’t know how comfortable people would be with an outside app aggregating that information.
Could you imagine if you got a monthly email from every site that had information about you?
I think that if I got a monthly email from every site that a) had information about me, and b) I expressly authorised to send me a monthly email asking if that information was still correct, that would not be too bad. Most sites satifsying (a) would fail (b). The only exceptions I can think of offhand are things like this, and dating sites.
