Uniform bounded generation conjecture for principal congruence subgroups

Let $R$ be a ring of algebraic integers with infinitely many units, let $I$ be a non-trivial ideal in $R$, and let $\Phi$ be an irreducible root system of rank at least $2$. Write $N_{I,\Phi}$ for the principal congruence subgroup and

$$Q(\Phi,I)=\{A\varepsilon_{\phi}(x)A^{-1}\mid x\in I,\ A\in G(\Phi,R),\ \phi\in\Phi\}.$$

Uniform bounded generation conjecture. There is a minimal constant $K:=K(\Phi)$ proportional to ${\rm rank}(\Phi)$ and independent of $R$ and $I$ such that

$$N_{I,\Phi}=Q(\Phi,I)^K.$$

This conjecture asks for a bound on bounded generation by a conjugacy-invariant collection that depends only on the root system, rather than on the ring or ideal. The supplied text gives no evidence that the conjecture has been resolved.
