Not necessarily. You can forward a lot of hardware as is to a Linux VM if you have an iommu. It comes down to whether you need multiple VMs to share access to some hardware or not, which is not all that common based on the way the isolation domains work out. This can start to become more challenging when that hardware has shared resources such as clocks, buses, or power rails to manage, but soc makers are likely going to make hardware increasingly easier to work in this modality as customers require it.
