AMD is not dropping support for the 5000 and 6000 series.

As most people were saying, what AMD is saying isn't that your game will not be supported, or that you cannot play games day one, or anything like that. You just will not be able to download and use FSR5. Is that still a dealbreaker for you? Cool. But everyone needs to stop scaring everyone into thinking their cards will literally cease to function starting today.
