When for verion >=5.0 we have:
V = Point{3, Float64}[[-1.0, -1.0, -1.0], [-1.0, 1.0, -1.0], [1.0, 1.0, -1.0], [1.0, -1.0, -1.0]]
f = QuadFace{Int64}(1,2,3,4)
 
Then requesting:
Now produces:
Quadrilateral([-1.0, -1.0, -1.0], [-1.0, 1.0, -1.0], [1.0, 1.0, -1.0], [1.0, -1.0, -1.0])
The original (when my compat read: GeometryBasics = "0.3, 0.4") and expected behaviour should return:
4-element StaticArraysCore.SVector{4, Point{3, Float64}} with indices SOneTo(4):
 [-1.0, -1.0, -1.0]
 [-1.0, 1.0, -1.0]
 [1.0, 1.0, -1.0]
 [1.0, -1.0, -1.0]
