I doubt that this will ever change. The limit of (theoretical) 15
overlays comes from the overlays the list view control offers:
http://msdn.microsoft.com/en-us/library/bb774760%28VS.85%29.aspx
The state parameter only has 4 bits for the overlay images, which
corresponds to 15 different overlays (or none). Since all other bits are
already in use, increasing the overlays isn't possible without breaking
compatibility.

If MS ever would offer more overlay slots, it would have to do so with a
different approach.
But then there's the problem which overlay icon to show if more than one
handler wants to show an overlay for the same item...
