Self-contained repros that avoid dragging in third-party code have at least two major benefits: they are more likely to be real bugs in the toolset, and they are significantly easier to investigate.
When I report compiler bugs (and due to the nature of my work, I file something like 150 per year), I try to reduce them all the way down to library-free repros, so the compiler devs don't need to dig through vast amounts of STL internals that they don't understand as thoroughly as I do. Reducing repros takes some time, but it's usually not very hard - I just have to throw away irrelevant code, but it's code that I'm familiar with, so I know how to chop it down. And in return, I get fixes quite rapidly. We don't expect customers to be able to reduce repros all the way down to library-free, but if you can chop out Boost, that really helps.
(For ICEs, preprocessed repros are usually sufficient, although smaller is always better.)
