I know what you meant OldDan43, so this is just for any reader or Googler who might be unfamiliar with GFCIs, not you :-)
One likely doesn't actually want "double protection" (or triple, or quadruple, or...), e.g. daisy-chaining GFCI outlet via the downstream terminals on a GFCI outlet. I haven't actually tried this at home, but if one trips, they are all likely to trip, which would be a pain to reset -- and could make isolating the source of the problem more work.
Instead, if one wants to feed multiple GGCIs off of the same circuit, one just taps the wire to each one along the way, nitbuaing the downstream connectors.
Personally, my general rule is not to use the downstream terminals on GFCIs. I like the convenience of having the reset nearby inbthe event of a fault and also of having only the faulting outlet disabled by the fault.
But, I do use the downstream connector when I can't or don't want to install a GFCI outlet, but want GFVI protection. For example, I have a power bar serving the galley bar seats. It isn't GFCI, but I wanted it protected. My choices were to run it downstream from an existing galley GFCI or to add a stand-alone no-outlet. I went with the former, even though it adenovirus the trip-domain larger, because I didn't want to waste the physical space on a stand-alone GFCI device.
