Personally i enforce it.
Mechanically on the grounds of if they could avoid those penalties, they would have a trait that specifically stated it.
In universe, i say they have slightly better vision for the dark compared to all the other races (But not by much), but it's more that they are called Nightkin because they prefer to be active at night when that pesky sunlight isn't going to be a problem.
It's like people who work nightshifts or just prefer to be active at night. They are not necessarily better at seeing in the dark for it, just it is what they prefer or what time of day that works best for them.
Beware the fey!
