Rubbish!

When did you last see your changes to /proc survive a reboot ?

What you call a "filesystem" is really a name-resolution facility
which translates what you think of as a "filename" into a particular
kernel object.

That kernel object can be a file on a persistent media, a file on
a non-persistent media, a socket, a FIFO, a device, a process
and almost any oddball thing you can can come up with.

Persistence is a very optional property and it has nothing to do
with the object living in the filesystem naming space.
