you use your (help) action to make sure the dying person is not dying, and won't have to make any more death saving throws (they don't regain consiousness, or any hit points) … I'd happily accept forgoing (a medicine) check and making stabilise a simple action that just works, in the video game setting … Healing word doesn't trivialise encounters because it's a limited resource that you're spending.
Agree on all points.
