Most faces don't change background color.  Only very special faces
(that are very rarely used in buffers on which occur is usually
called) have background different from default.  So any face with
a different background would be visible among highlighted text with
no background.

There is one problem with dimmed faces: they might be not readable,
especially for visually impaired users.
