But in the new default 'addition' mode the result is not pure white, because the 50% gray is not really 50% of the linear light value.
Maybe you forgot to set the color space of layer.
Besides image color space, to achieve 50%+50%=100% result, the "Blend space" and "Composite space" in Layer Attribute dialog must be set to RGB(perceptual) too.
I am a digital painting guy and prefer to work at sRGB color space. I can set all things to RGB(perceptual) to get what I want. But there is one thing cumbersome.
Whenever I change layer mode (the "Normal, Multiply, Addition,..." thing), the layer color space will always reset to "Auto", which is actually RGB(linear). I have to manually switch it to RGB(perceptual) every time. (In fact I wrote a Python script to do this automatically.)
