Pink–Zilber conjecture for curves in semiabelian schemes

Let S\mathcal{S} be a semiabelian scheme over a variety Y\mathcal{Y} defined over C\mathbb{C}, and let VSV\subset \mathcal{S} be a curve which is not contained in any proper algebraic subgroup of S\mathcal{S}. Define

S[2]:=yYBy,\mathcal{S}^{[2]}:=\bigcup_{y\in\mathcal{Y}}B_y,

where ByB_y is the union of all algebraic subgroups of the fibre Sy\mathcal{S}_y of codimension at least 22.

Pink–Zilber conjecture. The intersection VS[2]V\cap\mathcal{S}^{[2]} is finite.

This is a special case of the Pink–Zilber unlikely-intersections conjecture, extending Manin–Mumford-type statements to families of algebraic subgroups in semiabelian varieties. Its status is not specified in the source.
