Grunewald–O'Halloran conjecture for nilpotent Leibniz algebras

Let $A$ be an $n$-dimensional nilpotent Leibniz algebra with $n\ge 2$. A degeneration $B\to A$ means that the $n$-dimensional non-nilpotent Leibniz algebra $B$ degenerates to $A$. Grunewald–O'Halloran conjecture. For any $n$-dimensional nilpotent Leibniz algebra $A$ with $n\ge 2$, there exists an $n$-dimensional non-nilpotent Leibniz algebra $B$ such that $B\to A$. This is the Leibniz-algebra analogue of the Grunewald–O'Halloran conjecture for Lie algebras; the source mentions partial results in related algebra varieties but gives no resolution of this general assertion.
