At least for app snapshotting, migration and persistency this is «the must». They are not so necessary for containers themselves, there are support of some platforms without it, as well without dedicated layered FS (unions and similar like auFS/btrfs/zfs/etc - while it is good to have it).

Same like happens in Linux with our proposals related to openvz/namespaces/userbeancounters (after some time it became clear that they are necessary for modern OS). This is relatively cheap in implementation and overhead points of view.

I think your mental image of genode is at odds with reality. Genode is not another Linux (or comparable
OS). There are no processes. The most process-like entity in genode is the protection domain(PD). But the
PD is already virtualized. That makes it like a container with only one process. To share a namespace
between two PDs you have to explicitely configure that sharing. There are libraries that help you with
that and contain even some default naming of capabilities. But mostly you will have to setup the sharing
of a namespace by copying capabilities between PDs.
