It seems that mode-line-highlight is used for mouse-face.

How do you think to use it in which-func for keeping consistency
between other area on the mode line?

I think sometimes cursor is not sufficient. It doesn't tells just the
pixel under the cursor is something clickable. The feed-back with
mouse-face can tell the area under the cursor is something
clickable. Sometimes it is obvious that the area even without mouse
face. However, it may be a bit difficult to recognize one-character
area like area for buffer-coding system.
