I'm going to disagree on this a bit. I like cross-referencing as something that adds to, but isn't necessary to run a monster. So I think any monster should be able to be run without any cross referencing. However, if you use the cross-reference you can add another layer to the monster/encounter.The first is un-necessary cross-referencing.
One of the complaints some people had with 4e monsters was that they just couldn't do all the things you would want them to do as written. They only had onw or two powers instead of the list of spells or spell like powers from 1e - 3e. If you grew up on those monsters (like I did), then 4e monsters could look a little shallow.
So for me the ideal is a combination of the two. A fully functional and engaging statblock with out any references needed and then, for some monsters, a few references, in addition to the function statblock, that add depth without affecting its "CR."
It is clear WotC is heading this way (Biby's is a good example), not sure they will get all the way there.
