I don't see why you couldn't put that inside the completion function
that needs the cache, so you don't need anything special with
completers:

_xrandr() {                               # except this is the file _xrandr
   if (( $_xr_HISTNO != $HISTNO ))
   then
     _xr_HISTNO=$HISTNO
     _xr_output=$(xrandr -q)
   fi
 
   # use $_xr_output here
}
