Finiteness conjecture for genera of rational vertex operator algebras

Let VV be a rational vertex operator algebra, and let its genus consist of its associated modular braided tensor category together with its central charge. Write

gen(V):={isomorphism classes of vertex operator algebras with the same genus as V}.\operatorname{gen}(V):=\{\text{isomorphism classes of vertex operator algebras with the same genus as }V\}.

Finiteness conjecture. The set gen(V)\operatorname{gen}(V) is finite.

This asks whether fixing the modular braided tensor category and central charge leaves only finitely many isomorphism classes of rational vertex operator algebras. The source gives no resolution of the conjecture.
