People set up Stable Diffusion with automatic1111 and rocm for all kinds of weird setups successfully. What AMD needs to do is basically just provide a better out of the box experience, as even following the other people's instructions have been flaky at best. For example, for my 6600 XT, I have tried setting up SD twice. I succeeded in Manjaro in the past (like, a year ago), but didn't succeed now, and I succeeded in Debian now, but it uses the CPU for some reason. Hardware setup was the same, the only thing that changed is that I have updated my Linuxes in the meantime.
