I built a prototype that has one point primitive on a globe. If I use

VIEW_FRUSTUM_SIDES_CULLING then the point is displayed. But, as you
pointed out using only VIEW_FRUSTUM_SIDES_CULLING will disable cluster
culling.
In the meantime, I've implemented my own over the horizon culling to
solve the original problem.
Cluster culling should work, my suggestion for disabling just small
feature culling is all that should be required to fix things.
I suppose the question now becomes why does the point primitive
disappear when I use SMALL_FEATURE_CULLING with osgViewer?
The bounding sphere of the geometry will be projected into screen
space, if its smaller than the small feature cutoff size then it'll be
culling. A single point geometry will have a bounding sphere of 0
radius so will be culled.
