Yes I remember that bulletin & I have experienced it myself on a 200 basic. As I recall it wasn't a problem on the 200 advanced. Back then, it was a much looser deicing culture--no type 2, no specified hold-over times, wing anti-ice inop on the ground. You deiced at the gate, then sat 30 minutes in the lineup with precip falling & then you departed. Can't recall any accidents though--except on hard wing aircraft.
As for tail icing, the trimmable tailplane seems to eliminate this as a problem.
