When placing views into drawings we are quite limited in our options, unlike when in the 'Part' & 'Assembly' environments where both have a wide range of appearance options for us to choose from.
Options such as 'Realistic', 'Shaded (with no edges)', Shadows (on/off) etc. could be very handy for getting a nicer image onto the page without the headache of inserting/maintaining static images.
See here for a related discussion.
Now, I don't believe that my shopped image above is the best way to implement these features, it is just a way of getting the idea across.
P.S. I understand that a drawing with a few realistic/ray-traced views could be a real pig to manage but that would be up to the user to deal with, as it is with large/unwieldly assemblies that stress our machines.
