Termination of flips for compact Kähler gklt pairs

From papers

Let (X,B+β)(X,B+\boldsymbol{\beta}) be a compact Kähler gklt pair. A sequence of KX+B+βXK_X+B+\boldsymbol{\beta}_X flips is a sequence of flips for this generalized pair.

Termination of flips. Any sequence of KX+B+βXK_X+B+\boldsymbol{\beta}_X flips is finite.

Termination would imply the existence of log terminal models in the stated Kähler gklt setting, since the minimal model program can be run for compact Kähler dlt pairs with scaling. Termination remains open here.
