This is purely an insurance issue. The list of forbidden equipment, as laid down by the authorities and laid down by the airline are two different things entirely. Obviously, passengers are not going to stop transporting elctrical items in hold baggage.
I often put quite reasonably high value electrical items in the hold. Of course my employer is aware of this and neither they or I are complete morons so we have our own insurance which covers any eventuality. If I put a €15000 item in hold baggage then insurance liability is my responsibility and not the airlines.
