I think the MAX value does have some utility in the API -- as mentioned in other comments, if we're requiring that user space must SET all ranges at the same time, then we need an expected way for user space to SET a "don't care" or "MAX" or "null" value for a band. So if there's some new band (e.g., 6 GHz?) that user space was not previously aware of, it will know to use this placeholder. I think that's kind of approximately what the purpose of this was? It's not super clear in the documentation, so maybe that should be clarified in writing in v2.
