Seshadri constant conjecture for many points on a surface

Let $X$ be a smooth projective surface and let $L$ be a nef divisor on $X$. Let $\epsilon(n;X,L)$ denote the relevant multipoint Seshadri constant for $n$ points. Seshadri constant conjecture. There is a positive integer $n_0$ such that

$$\epsilon(n;X,L)=\sqrt{L^2/n}$$

for every $n\ge n_0$. This generalizes the expected value for very general points on the plane and concerns the asymptotic geometry of nef divisors and multipoint Seshadri constants; no resolution is given in the source.
