Depends lots on the center column design, not just how much the center column is raised/extended.
Typically, Foto tripods have flimsy center column designs (have a geared Gitzo center column, it is NOT as rigid/stable as believed) that are not stable/rigid. The better Foto tripods do tend to have improved center column designs yet they are still prone to instability and all that.
In the world of surveyor (Transit) , serious film making (Panavision, Arri, Red and...), Video tripods do NOT have a center column. More often they have a ball-bowl or very stable tilt mechanism. Adjust the legs as needed, level the tripod as needed, that variable center column was intended as a convenience feature, not a rigidity_stability feature. If the bag-O-stone to stabilize the tripod is applied, the tripod must be sufficient to support camera and bag-O-stones.. or not so lightweight tripod.
In all cases, mass = stability and that mass must come from some where, be it the camera, tripod or a bag or stones hanging from the tripod center or similar. Again, this is where focusing as the camera must be "lightweight" often ignores the overall demands of good image making.
