The GLND generation conjecture

Let $k$ be a field of characteristic zero. Let $\operatorname{GA}_n(k)$ be the group of polynomial automorphisms, let $\operatorname{LND}_n(k)$ denote the locally nilpotent derivations, and define

$$\operatorname{GLND}_n(k)=\langle e^D\mid D\in\operatorname{LND}_n(k),\ \operatorname{GL}_n(k)\rangle.$$

GLND generation conjecture.

$$\operatorname{GA}_n(k)=\operatorname{GLND}_n(k).$$

This is one of several proposed generation conjectures for polynomial automorphism groups by more understandable classes of automorphisms. Its status is not resolved in the supplied text.
