I haven't experienced the same issues you describe in terms of random beeping or the like. But I do think one of the most curious and irritating missing pieces from AirTags is no sort of tie-in with Family Sharing or some sort of contacts whitelist. I saw one thing saying that was about privacy but that makes zero sense because Apple doesn't do the same thing elsewhere in "Find My" for people or devices. While it's correctly opt-in, once everyone has done so we can see device locations for all of the family's stuff, which is very helpful when somebody is missing their phone or the like (anyone else can help with it) as well as checking in disasters. I don't see why that would be fine but keys wouldn't. In terms of privacy, someone is more likely to have their watch, phone or airpods on them then an Apple Tag frankly. Indeed that's the core logic of Apple Tags, we put down and misplace other random stuff but still have our phones/wearables. It can't be that rare for a family to have multiple vehicles where a certain amount of sharing happens, particularly if it's a pattern like us where the SO and I each have a car but then there is a single old truck that we both use. Family names are on the insurance, legally it's multidriver property. And even good friends/room mates probably share some kinds of property. Whomever has it is responsible for not losing it and thus has an interest in tracking it.

Yeah it's a v1.0, but even so when Apple already has all this infrastructure up strikes me as an odd omission that significantly detracts from the utility for no good end. Even a basic "ignore this tag for a day/week/year/permanently" would at least help sand down a bit of the most irritating notification spam. And worth noting that this sort of thing is a genuine security/privacy issue too: in real security systems, the human factor matters a lot. If people get spammed with noise, they will inevitably end up ignoring it when an actual signal turns up. We've known this forever.
