I'd prefer to keep backends simple, with 1:1 mapping to memory regions.
I agree. However not all backends may have a mapping to a RAM memory
region. A composite backend could create a container memory region
whose children are other HostMemoryBackend objects.
Is there a need in composite one or something similar?
I've heard of users that want a node backed partially by hugetlbfs and
partially by regular RAM. Not sure why.
