The standardness conjecture for prime ideals in solvable uniform Iwasawa algebras

Let $p>2$ be a prime, let $K$ be a finite extension of $\mathbb{Q}_p$ with ring of integers $\mathcal{O}$, and let $G$ be a compact $p$-adic Lie group. Its completed group algebra is

$$\mathcal{O}G:=\varprojlim_N \mathcal{O}[G/N],$$

where $N$ ranges over the open normal subgroups of $G$. A prime ideal $P$ of $\mathcal{O}G$ is standard if there is a closed normal subgroup $H$ of $G$ such that, writing $G_0:=G/H$, the group $G_0$ is torsionfree, $H-1\subseteq P$, and the image of $P$ in $\mathcal{O}G_0$ is centrally generated. It is virtually standard if $P\cap\mathcal{O}U$ is a finite intersection of standard prime ideals of $\mathcal{O}U$ for some open normal subgroup $U$ of $G$.

The standardness conjecture. Let $G$ be a solvable, uniform pro-$p$ group, and let $P$ be a prime ideal in $\mathcal{O}G$. Then $P$ is virtually standard, and moreover if $p\in P$ then $P$ is standard.

This conjecture seeks to reduce all prime ideals in solvable uniform Iwasawa algebras to augmentation ideals and centrally generated ideals. The supplied text gives no evidence that the conjecture has been resolved.
