In the blog for 6.6 (27 July 2021) future support of a dark mode is mentioned. Is there any progress in that direction?

Switching between Sweet Home 3D and Blender painfully shows how much better a dark mode is for your eyes, especially with the current early dark evenings . The interface and 2Dview have a lot of glaring white screen space which would be a lot less straining on the eyes with a dark mode.
