Works for me, I think some people expect that extra 0.5 spacing but if we view it as a point sample then the 1/2 spacing isn’t even quite right as it really is based on the point spread function of the sampling hardware/function which can be different from the spacing of the acquisition. Since we pretty much ignore the PSF in VTK then it’s fair game to just consider the bounds the actual bounds of the acquisition points. But still throws people all the time. And yes /agree on the pixel/voxel naming.
