AV1 hardware encode just started rolling out with the most recent GPU architectures so the majority of hardware still has to do software encoding. I'd also guess that a very large fraction of the hardware out there doesn't even have hardware decode for AV1 since it was only the last generation of GPUs that got that. AV1 is mainly solving problems for the platform owners (google/netflix/facebook etc) and h264 will probably serve typical users for years to come especially if they have that one device they want to keep using that only supports h264.
