The only reason you gave is that "you'll expect all NPCs acting like real human" with D/N cycle, which is totally useless to me.
No one will follow "random" NPCs or creatures and stay in game hours next to them exept those that want to say "hey, it's not a proper D/N cycle".
I believe the other reasons were the reasons the dev gave in the interview.
You're right in a way, it's about consistent illusions.
Just imagine this is another one because you'll only see what's on your screen...
A night appearing only when I click a button whatever I played for 1 or 10 hours is NOT consistent to me.
Isn’t this literally what happens in most RPGs with a day/night cycle? To prevent the player having to go and do something else for half an hour and time their return, they give a button to wait or meditate for x hours until whatever time they need it to be.
