The way Find My has been built, it doesn't really matter what they do with the tags, it's fairly straightforward to build your own tags, or modify tags, that bypass any stalking detection.

A phone's stalking detection just looks for a tag that's not yours that has been around you for a while.

But you can modify a tag such that it selectively powers up, or build a tag that changes identifiers, such that the stalking detection tools don't pick it up.
