Erm -- frankly, you completely missed the point.  This option doesn't
exist for a good reason: it's an accessibility _feature_.

If you really need to make it more visual you could still set
color/font/whatever based on a boolean value in the model.  Besides,
hidden selected rows weren't very "visual" either...

Hmm, seems weird (though a lot better than hidden selections). 
Admittedly I don't know enough about your application to tell whether
it's reasonable or not.  But please do at least consider my points, it
can't hurt.
