If the processes are isolated in a container, it makes it possible at some point in the future
to migrate the entire container
The PID problem fades into insignificance compared to the difficulty of migrating all the other state of a container - all the state in the kernel that uses the global kernel address space, such as inodes, plus the state that lives outside Linux, such as TCP connections and SCSI tasks.
I would wait until those problems are solved before complicating the PID namespace in the name of migration.
