I believe this fine fellow meant:

"I do say, I believe that 3D would be a great idea for SFML. It allow the user to make it easier for themself, lowering the requirement of other dependencies like OpenGL, and also, maybe allow for a simpler method of use than said dependencies."

;D

Please search before post, the topic 3D has been discussed numerous times and the answer will never change... ::)
SFML only provides 2D functionality period.

Also OpenGL is always needed with SFML but you don't have to explicitly link it, except if you were going to do some custom drawing.
If you want 3D you can use some other simple libraries like Irrlicht or do everything on your own with SFML as window 'creator' and OpenGL. (Same answer as in the other thread of yours)

Also it seems you've no idea what exactly lies behind 3D programming and just want to use it because it looks cool etc. Game programming is quite complex even in 2D but with 3D you need to take care of a lot and it's not just adding a few more lines of code....

3D is easy with OpenGL && SFML;
SFML integrates OpenGL to the heart's content ;D

Heres your few more lines of code ???
C++ rendering with OpenGL:

void RenderWindow::BufferObject(DisplayedBeing3D *mesh){
        if (mesh->_Culling){
                glEnable (GL_CULL_FACE);
                glLightModeli( GL_LIGHT_MODEL_TWO_SIDE, 0);//cull lighting
        }else{
                glDisable (GL_CULL_FACE);
                glLightModeli( GL_LIGHT_MODEL_TWO_SIDE, 1);
        }
        
        if (!mesh->_Anchored){
                ApplyGravity(mesh,_TimeBetweenFrames);
                ApplyVelocity(mesh,_TimeBetweenFrames,0,_LengthOfMeter);
        }
        glBindTexture(GL_TEXTURE_2D, *mesh->GetTexture());
        glColor4f(1.f, 1.f, 1.f, 0.f);
        if (mesh->_SmoothShading){
                for (unsigned int i=0;i<mesh->GetFaces()->size();++i){
                        if (mesh->GetFace(i)->GetSize() == 3){
                                glBegin(GL_TRIANGLES);

glBegin? No thanks. :P

Also, glLightModel, glColor, glNormal and other unpleasant things from the dark ages.
