Why is HLG ISO 100 but S-LOG ISO 500?

One of the drawbacks of using these flat picture profile gammas (wider range) is that they sometimes comes with limitations on ISO. For example my A7C's lowest ISO for S-LOG is 500, and my DJI Mavic 3's lowest ISO for its D-LOG is 400...

HLG mode (HDR) however, which is the widest dynamic range that Sony have, actually supports ISO 100. Why is that?
