Yeah, it's just a silly exploit. A better way should be implemented to guarantee that the luggage won't die.

Done: Mithion/ArsMagica2#275

Well, Luggage does have finite health, it's just that isEntityInvulnerable() returns true, and thus Minecraft doesn't damage it. But how to make this better...?

AM2 should be doing checks. Were doing everything correctly afaik.

I think AM2 should be checking too, since this isn't just a problem of cross-mod, but actually an feature of vanilla that custom Maps also make use of.
