I'm not sure what change you're suggesting. Is it to always create a leaf if nPrimitives <= maxPrimsInNode? I tried that change and for the two scenes I tried, saw a 10%-30% slowdown.

Yeah. Right.
I am using the acceleration structure for raytracing volumetric data and by this change I got performance improvement. I don't remember how much was it. But logically, it makes sense to always split when the number of primitives get smaller than maximum primitives in the node. In the example above, what performance improvement do we get by splitting? I think it makes sense to not split.
