See the thread on creating tasks in userspace vs. kernel space:
the argument here is that is an interesting enough use case for
a checkpoint of not-an-entire-container.

Of course it will require more logic to it, so the user can choose
what she cares or does not care about, and the kernel could alert
the user about it.

The point is, that it is, IMHO, a desirable capability.
