I can't speak for other people, but I use this kind of functionality in 
nearly every plot I do.  Usually I contourf a field in 4-level 
greyscale, then contour over that to make 8 contour levels, then 
contourf over _that_ to mask land points (I run models so I have 'land' 
arrays I can use for this).  Sometimes I them put polygons (sometimes 
transparent) over that to highlight regions.  Usually how I've been 
doing this is by going in to illustrator and manually altering the 
stacking of the plot elements.  Ideally how I wish it worked was that 
the default zorder was set by a counter, so the oldest plots on an axis 
would be buried under the newer ones.
