You are mistaken. Merchants are allowed to round to the nearest 5 cents and you can’t do anything about it (except pay by card). Of course, budget stores like Lidl and Aldi still use them but any other corporation is not going to care.
Thanks for the correction. So only the part about legal tender was correct, which is probably what I was confused with. The relevant part:
> The one and two cent coins will remain legal tender, and retailers can choose whether or not to participate. The Netherlands cannot declare the smallest coins worthless on its own in Europe; this must be arranged in Brussels.
