I don't think that it is unique to KLM. I realize that company policy for many airlines in Class G is use RAS (on their terms).
However, I remember another airline operating in the middle air across the North Sea. One crew under a RAS from me elected not to take the turn offered to them with traffic info that I issued on a pair of F15s doing intercepts off the Norfolk coast. The traffic turned towards them and started to descend; with the a loss of warm fuzzy feeling and the fact that said airline pilot had not yet called visual, I re-issued traffic information. This time the pilot did call visual with the F15 at a range of about 10-15 miles. Both ac continued on their flight profiles and the F15 overflew the civvy with a couple of hundred feet separation.
You can probably guess the outcome. Airmiss (it was a few years ago!) filed by the airliner. How to shoot yourself in the foot eh!
