I think that is the reason.
HT isn't going to make a doctoral dissertation out of this decision.
In the beginning, there was no night. Then folks cried for night. They got it. Other folks cried to change it back to all day. Now other folks are crying to get night back.
I think HT just figures it's good to share.

Night will come back at some time. How long was it in? Maybe the cycle time will be standard.
I'm not upset a bit. I suffered through night during Prime Time when that was the only time I had to play many, many times and for quite a long period of the game overall.
Now some folks can suffer through the outrage of daylight for a similar period. They should feel free to complain as we night-haters did, and as the night proponents did so long ago to get night.
Fair is fair, eh?
I'm guess fair isn't what you're interested in though. Am I right?
