You point is from service developer. But for system administrators this
nothing changes on fact that systemctl syntax is insane tedious.
I must have in root .bashrc some as this helper:
function a(){
  [[ "$1" =~ (\?|-h) ]] && {
    echo -e "1st param:\n -nothing-\tlist-units|grep
\.service\na\t\tlist-unit-files\nl\t\tlist-unit-files|grep \.service
2nd param(1st=service):\n
-nothing-\tstatus\ne\t\tenable\nd\t\tdisable\nr\t\trestart\ns\t\tstart\nk\t\tstop\n"
    return; }
  C="--help"; unset S
  if [ $# -eq 0 ]; then C="--all list-units"; S="|grep '\.service'";
  elif [ $# -eq 1 ]; then [ "$1" = "a" ] && C="list-unit-files";
    [ "$1" = "l" ] && { C="list-unit-files"; S="|grep '\.service'"; }
  else
    C="status"; S="$1";
    [[ "$1" =~ \. ]] || S="$S.service";
    [[ "$2" =~ ^e ]] && C="enable"; [[ "$2" =~ ^d ]] && C="disable";
    [[ "$2" =~ ^r ]] && C="restart"; [[ "$2" =~ ^s ]] && C="start";
    [[ "$2" =~ ^k ]] && C="stop";
  fi
  eval systemctl $C $S
}
