I think you're missing why ++ could be useful, and it's precisely because
Ruby is a "21st century language"

The ++ operator, far more than just being syntactic sugar for +=1, would
allow you to send an "increment" message to any object, which would change
its value in place, i.e.

  def ++
    incrementing_logic_goes_here
  end

I could see this as being handy
