I don't expect to see it in 2077, but I reject the notion that it's a bad idea in general. Perhaps you don't care about roleplaying, perhaps you don't care about immersing yourself in a role you've created for yourself (Without a linear story guiding you), perhaps you don't care about exploring a virtual world in said role, at your own pace and in your own way...
See, I can do that too.
I would never ask for radiant quests at the cost of actual CDPR quest quality or quantity. I
would ask for it in place of meaningless, copy-paste nonsense like horse (sorry,
car) racing, fist fighting (sorry, boxing), and the shooting range (how is that even a minigame?). Presumably, like The Witcher 3, once you've finished the questlines for each of those activities, they're done -- you can't do them anymore, period, end of story.
That's where radiant stuff comes in. It gives you a way to continue hanging out in a world and living out your character's life. It obviously won't happen, though.
