First, are these page in or page out operations? Page out operations are asynchronous and therefore of no concern.
I'd dig a little deeper, and, if the average page in rate is zero, I'd rest easy.

This is most noteably seen by using SDSF Display Active and using "sort paging d (escending)". It is only swappable adresspaces that pages. Does SRM still do "working set trimming" before doing a logical swap? This last only a few seconds, and then there is a new burst with some other adrspaces. Is there a way to avoid this without making everything Nonswappable? The adrspaces that is paging is typically MQCFG and USS ardspaces. In general, the paging rate overall is close to zero. Appreciate any feedback.
