For medical issues, I agree that private is usually best; or at least restricted to close friends and family. Imminent death often has an adjacent position, where people commonly wish to share with a broader audience. However it was just an example of an emergency where one might strongly desire to update a broad range of friends and family quickly. Other situations might be natural disasters or a house fire where one "We're alive!" post might require a follow-up the next day with more details, needs, or grief. It's just to say that an unyielding, global rate limit would not serve peoples' interests well.
