Ulrich wildness conjecture for general linear standard determinantal schemes

Let $X\subset \mathbb{P}^n$ be a general linear standard determinantal scheme of codimension $c\ge 2$ defined by the maximal minors of a $t\times (t+c-1)$ matrix with linear entries. Ulrich wildness conjecture. $X$ is of Ulrich wild representation type unless $X$ is $\mathbb{P}^{n-c}$, the rational normal curve in $\mathbb{P}^n$, or the cubic scroll in $\mathbb{P}^4$, which are of finite representation type; or the quartic scroll in $\mathbb{P}^5$, which is of tame representation type. The preceding theorems, corollaries, and computational examples prove the assertion in many cases, but the general statement remains open.
