This feature will never be implemented for braw, because ISO is not a tool of exposure. It's just metadata, which applies a display curve to the footage (one alterable in post) but isn't altering the exposure of the sensor, which is determined solely by the f-stop and shutter speed. Whether the ISO is 100 or 1000, the exposure is the same if the f-stop and shutter speed is the same.
If you're talking about movies, you're not going to want to fool with shutter speed for every shot, so the only way to achieve a particular fx is the f-stop.
Even if you're shooting Prores, you really don't want to rely on the ISO as a tool of exposure, beyond choosing one of the two circuits based on overall lighting levels.
