I suspect the ROCm situation has not improved since last time I checked, based on their documentation. The installation guide [0] is a bit of a mess. It looks like they are targeting ROCm at existing ROCm users rather than finding ways to convince people to become ROCm users; nothing there is useful introductory material. The opening is basically marketing babble too. Or possibly someone with a history in the GNU projects lineage of terrible recursive names.
It just doesn't look like they've got a leadership figure trying to bring people in to their ecosystem right now. I dunno, maybe the API isn't intended for interested developers.
[0] https://docs.amd.com/bundle/ROCm-Installation-Guide-v5.4/pag... - opens with "ROCm is a brand name for the ROCm open software platform (for software) or the ROCm open platform ecosystem (includes hardware like FPGAs or other CPU architectures)".
