You'd have to do some serious convincing, explaining why we absolutely
need the exponential stuff.

Most devices today use linear brightness, and userspace needs to know
the relation, especially for RGB stuff.

You can set bigger max-brightness, and then do in-driver conversion to
use full dynamic brightness range...?
