Seems quite dangerous. In my country, this was the norm for local flights - usually smaller planes, 1-2hr flights. It was common that if you could not attend a meeting, a colleague would go with your ticket. Nobody cared.

Then one plane crashed. And some passengers weren't insured, as they were not officially on the plane. Those families could not get a body back, nor any compensation, as the company said that they could not prove they were on the plane.

I don't read the small print of IATA when getting a ticket, maybe I should someday.
