I am not a specialist, but isn't any journaled filesystem need stable pages to store the journal itself?

Yes; but unstable pages are modified by applications after calling write() without notifying the kernel.
I'd hope that pages containing journal data are not exported to userspace, and that filesystem code knows what it's doing.
