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.
