It is interesting to see that it works at all on RDNA3, albeit with huge performance hit compared to FSR3.1.

Which is probably the reason why AMD didn't release FSR4 to RDNA3 or even older cards. It's barely better than native, so I can understand that AMD didn't consider it worth the trouble, especially when they have other software parts where they need to catch up to NVidia. 

Yeah, performance gains over native are quite modest compared to FSR3, though those 33% are nothing to scoff at, given that FSR4 looks really good. So at least, for this particular niche, high end RDNA3 owners on Linux, there is viable, though costly, alternative to FSR3/XeSS.
