Support-variety criterion for wild blocks of Lie superalgebras

From papers

Let C\mathcal{C} be the representation category under consideration, let B\mathcal{B} be a block of C\mathcal{C}, and let SBS\in\mathcal{B} be a simple supermodule. Write Vg(S)\mathcal{V}_{\mathfrak{g}}(S) for the support variety of SS.

Support-variety wildness conjecture. If there exists a simple supermodule SS in B\mathcal{B} such that

dimVg(S)3,\dim \mathcal{V}_{\mathfrak{g}}(S)\geq 3,

then B\mathcal{B} has wild representation type. This conjecture is motivated by the analogous finite-group-scheme result and would connect the constructed support varieties of classical and Cartan-type Lie superalgebras with block representation type; the source gives no resolution.
