Steve, I clearly see your point.
But, my only contention was that this receptacle contains ground fault protection for persons [GFCI] with instructions that clearly show connection diagrams with only other non-gfci receptacles connected downstream of it. IMO, installing a second GFCI receptacle downstream of this first GFCI receptacle would be a violation of the listed instructions included with this first receptacle.
This is no way should be construed as saying that you couldn’t have another piece of listed equipment with its own GFCI protection utilized downstream, but I don’t believe that a second GFCI receptacle would be allowed, at least according to the included instructions.
