It might be helpful to climb up a few levels in this thread ...

I think we all agree that containers are not a kernel construct. I further
believe that the kernel has no business generating container IDs, those should
come from userspace and will likely be different depending on how you define
"container". However, what is less clear to me at this point is how the
kernel should handle the setting, reporting, and general management of this
container ID token.
