But that wasn't your comment/question. You asked if my original answer would apply to CMMA, and I said no, it would not apply to CMMA, since that is an architected interface between Linux and z/VM, implying that the drop cache /proc interface is not. And indeed it is not. Using CMM-1 (and possibly CMMA/CMM-2 if you're brave enough) will achieve real storage savings and, unless mis-handled by VMRM or the system administrator, not adversely affect performance of the Linux guest. Using the /proc interface to drop cache and buffers is not recommended in a production environment.
