I guess you never got up to Europe very much, eh?
Well, lets see.
FRA, too many times to count.
Stockholm
Copenhagen
Paris
London (yeah I know, not much icing there)
Munich
Vienna
Zurich
Geneva
Amsterdam
the list goes on and on....and on

I will repeat, wing anti-ice in a 'proper' swept wing jet transport airplane (possible exception B737, IE, the 'junior' jet) is simply NOT needed.
Heavy jet ops prove same, without a doubt.
Next?
NB.
Spooky appears to be 'out to lunch'...
