ROCm 5.5 will be the first release to officially support the 7900XT and 7900XTX, so not having this potentially causes issues for users with recent AMD hardware. (See https://github.com/RadeonOpenCompute/ROCm/issues/1880 for extensive, related discussion).

This is entirely based on speculation that ROCm 5.5 won't introduce other breakages before its release though, so I'd totally understand if this is not a satisfactory solution.

It shall be complimented by the device-lib change in the corresponding release, so it is not that simple.
