Someone proposed to have a _distinct color for status "unmaintained"._
Status "unmaintained" is currently signalled with gray color, the same
as for status "unknown"
The current color scheme can be found at the lower part of page:

The proposal was added here:

and somehow related is

Because such a color scheme change can have a wide impact and unwanted
side-effects, I cross-post the proposal here.
