comment plane cubics and conic bundles
Thank you! so everything I stated stays true for nodal curves: cool.

I don't know how to edit the comment, actually it is hypersurface, not surface of course.

comment plane cubics and conic bundles
For the smooth plane cubic, the net of conics is given by a surface of bidegree (1,2). The problem is equivalent - I think - to checking wether all nodal plane cubics are symmetric determinantal. This seems quite true....
