Bilinear Kakeya range conjecture

Let $n\geq2$, let $K^*(q'\times q'\to p'/2)$ denote the bilinear adjoint estimate associated with the discretized x-ray transform, and let $1\leq p,q\leq\infty$.

Bilinear Kakeya range conjecture. $K^*(q'\times q'\to p'/2)$ holds if and only if

$$p\leq n,$$ $$\frac{n-2}{q}+\frac{2}{p}\geq1.$$

The source presents this as equivalent to the Kakeya conjecture after interpolation and bilinearization. The source gives no resolution status.
