It would be nice if the Sun light would default to real world values.
When the sunlight has correct values, you can set your camera exposure settings to values that actually make sense in real life.
You should be able to follow a “sunny 16 rule chart” for exposure values.
As it is now, different “groups” are working with different arbitrary values.
This often results in compositing artefacts and glitches for third party implementation.
(In various VFX and broadcast industries.)
If everybody knew form the start what values make sense in real world.
Then you would avoid situations where lighting works in one application, but then breaks in another.
