I love the idea of check-in policies, but there are just some scenarios where you want to apply them on one project, but not another in the same solution. One obvious instance of this is with test projects. I'm all about some code analysis, but it makes no sense to waste the time applying or even scanning for code analysis violations. For this, I'd really like the ability to apply check-in policy exceptions to certain projects. This would make check-in policies much easier to deal with.
