This would be neat but a lot of people would say it’s immersion breaking or they would have to come up with a new climbing mechanic. They would also have to redo all the terrain and invisible walls they have set up. So in other words this would take a ton of time for developers and it’s something in sure they wouldn’t have time to do.
This, I’m afraid.
The terrain is as such for a purpose. It’s better than having invisible walls (because there’s nothing more immersion breaking than that). Having things blocked off is important and serves a number of purposes:
-limits map size
-stops players wandering to a part of the map which hasn’t been designed as playable (could be prone to bugs/terrain glitches)
-stops players “exploiting” areas, such as skipping parts of a jumping puzzles/event chains/bosses
And as for the advantages you listed? Well… it is fun to explore, and to get good views, but we already have plenty of those in-game. Vistas, jumping-puzzles, diving goggles, gliding… they all kind of serve this purpose. People are always looking for a higher place to reach, and no matter what method has been added by developers to reach a high place, players will always use void jumping (and other “non-immersive” techniques) to get there.
