McKernan's ACC conjecture for interpolated thresholds of nested foliations

Let XX be a normal variety of dimension dd, and let FGTX\mathcal{F}\subset\mathcal{G}\subset T_X be foliations. McKernan's nested-foliation ACC conjecture. For every positive integer dd, there is an ACC set Γ=Γ(d)[0,1]\Gamma=\Gamma(d)\subset[0,1] such that

sup{t[0,1](G,F,t) is lc}Γ.\sup\{t\in[0,1]\mid(\mathcal{G},\mathcal{F},t)\text{ is lc}\}\in\Gamma.

This is presented as a more general version of the interpolated lc-threshold ACC conjecture and remains unresolved in the stated generality.
