This wouldn’t really be any different from using the cell network to transmit the data.

It is different, because this doesn't need cellular connectivity and can even bridge air gaps. Afaik, your iPhone will happily cache found FindMy beacons and send them out once it has internet connection again.

It's pretty undetectable even by Apple due to the way Find My works.

The receiving of the data, not the sending is the most detectable part. Because you need to modify a Mac app to get the raw data.
