Would it be okay if we didn't do this for default behaviour?

Nvidia's state-of-art compiler is `nvcc` and it uses `ptxas`, not JIT. When comparing the performance of MLIR, it gives sanity to use same toolchain as `nvcc`. I had problems using the driver for JIT, which produced different SASS code from the exact same PTX, even though it was the same version with ptxas.
