Introduce 4K 4:2:2 IPB 400Mbps and FHD 4:2:2 IPB 200Mbps modes for Panasonic GH5

Current (at the moment of writing) highest quality compression modes supported by GH5 are 4K/C4K/4KA 4:2:2/10 IPB 150Mpbs and FHD 4:2:2/10 100Mbps. There is a plan to introduce 400Mbps ALL-I compression later in 2017.
What is missing from the camera (and plans for firmware updates) is a support for a really high quality compression of 4K/C4K/4KA 4:2:2/10 IPB at 400Mbps and FHD 4:2:2/10 IPB at 200Mbps. ALL-I 400Mbps compression that is planned to be introduced this spring, requires much higher bitrate for the same image quality so this update hardly brings any image quality improvements. Only the introduction of the high-bitrate IPB modes provides the image quality required to make this camera a true jewel of videography. Such upgrade would also make the in-camera recorded VLog-L footage more gradable.
This petition is aimed at proving Panasonic that the demand for such feature is high.
