Code-hopping remotes have existed for a very long time, and I am really surprised that it's not the case here. I have had cars that were made in the 90's that used keeloq, a technology from the mid 80's.
In fact, all of my door openers and car remotes have some form of code-hopping and it's certainly not because they were specifically chosen for that aspect.
Sure, there are attacks for code-hopping systems as well, but it's a completely different league.
By code hopping do you mean rolling code based remotes?
I think what can sometimes be done with these is that one can record one or two codes and then desync the original remote. But I agree, it's a different league.
