I use mine but put them inside a nice leather tag with a flap so you can't see what is inside unless you make a point of looking. I too am not a fan of putting BAEC tags on luggage for all to see (smacks a little of DYKWIA to me) but they do serve a purpose if they are needed.
As for identifying my luggage... red cases make by Jeep... very easy to identify even from 100 paces!
