Yes I should be able to find a device or 2 which poke GPIOs from the VBT MIPI sequences. Unfortunately I don't know from the top of my head which devices actually use this, so I may need to try quite a few devices before finding one which actually uses this. I'll try to get this series tested sometime the coming weeks, depending on when I can schedule some time for this.
