As there is limited discussion on this topic, two weeks ago, vkd3d-proton merged a change that disabled all types of emulation paths for FP8 that made it possible for RDNA2/3 to run the "official" FSR4 model. Note that this does not affect people running the leaked INT8 model or other modified DLLs.

This decision is above my paygrade and it's done to work toward being able to support FSR4 more officially in Proton.

Custom builds of vkd3d will be required going forward for anyone who wants to use the FP8 model on older hardware. I'm unsure if the main forks (GE/EM/cachyos) already do this so they may be unaffected.
