I see, it is called when setting the face foreground/background via the customize menu.
I've tested it, and it works still perfectly fine (as expected... predicting the expected
effects/implications in this case seems quite straightforward to me).

Do we have any data from e.g. GNU ELPA, MELPA, GitHub or something to
back that up?

I checked, and we have only one call to `list-colors-display' in the
Emacs tree: in `widget-color--choose-action'.  Does that function still
work as it should with your patch?
