I don't know.

I think they just want a way to set a per-buffer window-background
color, in a way that affects the area after EOB as well as the buffer

This should be achievable by doing something like:

   (face-remap-add-relative 'default :background "blue")

... as the `default' face is supposed to be used for everything
including the EOB area, but this doesn't work properly because of the
above-mentioned bug.


Run away!  Run away!
