Hopefully the RDNA3 software stack is good enough that AMD decides that CDNA2 (or CDNA-3) can be based off of the RDNA-instruction set.
AMD doesn't want to piss off its $100 million+ customers with a crappy software stack.

BTW: AMD is reporting that parts of ROCm 4.3 are working with the 6900 XT GPU (suggesting that RDNA code generation is beginning to work). I know that ROCm 4.0+ has made a lot of github checkins that suggest that AMD is now actively working on the RDNA-code generation. Its not officially written into the ROCm documentation yet, its mostly the discussions with ROCm github issues that are noting these changes.
Its not official support and its literally years late. But its clear what AMD's current strategy is.
