Of course, I get it from Apple's perspective, they dont want AirTags to be used to tail others. However, that precludes it from being used for theft tracking.
For example, I use an AirTag on my bicycle. If someone steals the bicycle, they are literally informed "an air tag is following you" https://support.apple.com/en-us/119874
There are a lot of things I'd love to put long-term AirTags on (luggage, snow-blower, childrens' backpacks) but if theft isnt really deterred, then the case for a bulkier AirTag is quite reduced.
