I am actually fine with there not being a day/night cycle if it doesn't really add anything .
Well, if you set a questionable premise you can draw questionable conclusions from it.
The thing is: a day/night cycle even at its bare minimum almost inherently adds to the setting, which is precisely why people now have to come up with dozens of convoluted little solutions only to PARTIALLY fill the gap left from the absence of the feature.
For instance the lack of cosmetic variety, having to handcraft custom encounters happening specifically at night, having to come up with solutions that can help suggest the passing of time in other ways, creating the condition to allow for encounters with night-exclusive creatures, etc, etc.
