Here we are - 3600 which was still under manufacture 2-3 years ago are not get patched. Shame on you AMD, if it is true.
Maybe they’ll reverse course with enough blowback, they did that once with ryzen already, don’t remember which Gen it was but it wasn’t going to be backwards compatible with certain type of mobos, but then they released it anyway and some mobo manufacturers did provide bios updates to support it.
Similarish situation could happen here, the biggest hangup I’d think is that the 3000 series is nearly 5 years old, and getting mobo manufacturers on board for that could be difficult.
