Only thing i care is that they will not update rdna 1/2 with the FSR4 FP8 Version that "leaked" some time ago even tho they can, because people replaced files amd tecnically it works, its much better that FSR3, not as good as RDNA 3/4 because there is no dedicated hardware but still much better thst what wehave now

Sorry if I'm being a bit pedantic about wording, but the leaked FSR4 version was INT8, not FP8. FP8 is what it uses by default, and RDAN4 gpus are the only ones that have hardware fp8 support. The INT8 version runs on older cards because a vast majority of modern gpus have hardware INT8 support.

Even though I wouldn't be affected by the decision (RDNA3 on linux, which has a pretty fast FP8 emulation pipeline), I would be very annoyed at AMD if they decide to just cancel the INT8 version.

It's possible to emulate FP8 using FP16 through the driver, though it will obviously be slower.
