The SLIN conjecture for special polynomial automorphism groups

Let ${\rm SA}_n(\mathbb{K})$ denote the group of special polynomial automorphisms, and let ${\rm SLIN}_n(\mathbb{K})$ denote the corresponding subgroup satisfying the special linearization property. SLIN conjecture. If $\mathbb{K}\neq\mathbb{F}_2$, then

$${\rm SLIN}_n(\mathbb{K})={\rm SA}_n(\mathbb{K}).$$

This is presented as a slightly stronger conjecture than the Maubach–Poloni conjecture. The source does not state a resolution, so the conjecture remains open.
