One tiny fly in the ointment is that the 6.6 mainline release 2023-10-30 will with a very high probability become the next Long Term Supported linux kernel and then it will be another year before the next LTS kernel is selected. The reason is that it usually takes 9-10 weeks for the next new mainline kernel to be ready, so that would be early 2024 before 6.7 would be a mainline kernel and historically the LTS kernels are announced between October and December.
Earlier versions of those patches have been submitted quite for a while now. But submitted doesn’t mean accepted. There is ongoing discussion about those patches here: https://lore.kernel.org/lkml/?q=JH7110
