I am talking about ambient_occlusion_gamma and the light decode table:
https://github.com/minetest/minetest/blob/90fccc15ebf86b58656c28ed9853780d92feb69e/src/light.cpp#L59-L60

Why?
These are currently hardcoded or at least only client-controllable.

Usecase?
In Minetest Classic I want to change these to make the result looks like Minetest 0.3 did.
But this feature would be very versatile.

Open questions

• What to make of the existing client-side settings?
