Has Lego discontinued presenting alternate configurations on the backs of modern boxes? When I was younger, the backs of my Castle/Space Lego set boxes showed alternate model builds for the supplied pieces, configurations not detailed in the instruction manual.  I appreciated these creative ideas, showing me other things I could make with the pieces; I found them inspiring and sometimes challenging as they were presented without instructions.  The inclusion of these models made me keep clippings from the boxes in order to replicate designs.

Today, it seems that alternate model designs are no longer presented on the backs/sides of Lego boxes.

Has Lego discontinued this practice, and why?  Has it been dropped entirely for all sets, or is it simply not done for "licensed" sets (Batman, Star Wars, etc.).
I don't have enough reputation to post a comment, but in response to this comment by user3509 (and the similar answer from MartenFerret):

I would also hazard a guess that for brand sets part of the deal was that alternate models weren't allowed for copyright reasons - for example, a Star Wars X-Wing set can only build an X-Wing. Lego then probably made all sets follow the same design pattern for their own brand cohesion.

The original 7140 X-Wing model released in 1999 did have the traditional alternate builds shown on the back of the box:

So if it's a licensing-based decision, it was a later one.
