If you are operating a custom hypervisor environment there is security
and maintenance value in minimizing the kernel code enabled.
So eg needing iommufd turned on to run qemu and vfio but also needing
vfio container & group turned on to run dpdk as part of the OVS is not
desirable compared to just updating dpdk.
