If nothing else, it shines light on the fact that some project teams may
not be practicing license oversight as much as the rest of us would like
them to.

This is not surprising to me, but it might be worth adding to review

It's also entirely possible (shock!) that people haven't actually read

to mix these licenses together. Heck, even after this discussion, I'm
not really sure whether or not it's OK.
