There are costs in performance and possibly hardware depending on the configuration used to set up a GRS ring (although things have changed over the years with sysplex, GRS over XCF etc.). I'm not advocating doing this, but I have been at lots of shops that do so. As long as they know the risks and can manage them, I don't see the problem. Several of my long time clients in small shops did the same thing for their sysprog sandbox LPARs. Considering only 3 or 4 people (sysprogs) could ever logon to those test systems, I would say the risk was very managable.
