The only new inhabitants they can get there are virtual ones 😄
I checked the lap times, and can you imagine that the last 3 laps (≈ 40km) were raced slower by leaders than on the U23 race?! (and their fastest circuit laps were when Armirail🇫🇷 was pulling as a domestique!)
Those guys exhausted themselves before that, when Van der Poel🇳🇱 was ahead, I'd say. Especially Del Toro🇲🇽 and Seixas🇫🇷, who both started experiencing troubles at the same point, and started ingesting anything they could find in panic mode.
Also contributed to the low final speed the fact that their pace was switching ON-OFF-ON-OFF-... all the time in the last laps.
