banning as in banned, illegal, no sell, no buy, no use etc
Not possible, sorry. You can't retrospectively apply a law like that. If something has already been made, then they can't stop you using it. For instance, emissions laws change and a car a few years old might fail new standards, but they can't make you take it off the road, however much they try.
Older racks will be maufactured to some staadard or other I imagine, and the same will apply
I guarantee that if they have to stop making them, you'll be fine usng the one you already have.
That said, I wouldn't use one again and I can see why someone might want them banned.
