I'd say that the important thing is to hide them from reads. It would
probably not matter if they listen to writes or not, as long as the
writes also goes to regular memory and also long as it's consistent
(i.e. once it's a product ready for consumption by anyone this shouldn't
change as that might cause confusion).
