For $m<n$, in the non-generic regions corresponding to lower dimensional faces of $Sk(X)$, the NA MA solution is expected to lose information about the metric. One expects instead that Ooguri-Vafa type metrics constructed using the generalised Gibbons-Hawking ansatz become important [25][42][31]. It would in particular be very interesting to understand the next generic behaviour, namely how the transition across $(m-1)$-dimensional faces of $Sk(X)$ occurs in general.
