As I said before, since these are static entities, you build a
program that does a static dump of a procfs into a directory tree.

You put them wherever you like on the disk. No, there's no link.
On the other hand, if you send the output of ps to a file, you
don't have any link between that file and the kernel/kmem that that
ps output came from either.

The statically constructed procfs stays there until you delete it.

Seems to me in this case it's a matter of opinion.
