Source? Afaics it's more like: Yes, GCN is considered experimental, but even if you enable the amdgpu support for CIK parts you have to provide two module parameters on boot to activate it -- hence you can't really call that "Sea Island cards are enabled by default" imho. See https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/drivers/gpu/drm/amd/amdgpu/Kconfig for details (it's the same in 4.13). That stuff was changed quite a bit for 4.13; one of those commits was https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=2b059658d6796a096ef06be9da994d6c44401d5b which reads "There is no feature parity yet for CIK, in particular amdgpu doesn't support HDMI/DisplayPort audio without DC." For me all of this says: It's way to early to switch to amdgpu for GCN or CIK GPUs.
