D-module and nilpotent limit categories for genus-zero vector bundles

Let $C=\mathbb{P}^1$ and let $\operatorname{Bun}_{\operatorname{GL}_r}(0)$ be the degree-zero component of the moduli stack of rank-$r$ vector bundles. Let $\operatorname{IndL}_{\mathcal{N}}(\mathrm{Higgs}_{\operatorname{GL}_r}(0))_0$ denote the neutral component of the nilpotent limit category. Genus-zero limit-category conjecture. There is an equivalence

$$\mathrm{D\text{-}mod}\left(\operatorname{Bun}_{\operatorname{GL}_r}(0)\right)\simeq\operatorname{IndL}_{\mathcal{N}}\left(\mathrm{Higgs}_{\operatorname{GL}_r}(0)\right)_0.$$

This is proposed as the automorphic counterpart of the trivial genus-zero degeneration on the spectral side. No resolution is supplied in the statement.
