Does this have (additional) implications for caching tools and modules? They cache diagnostic output, but if these other paths showing up or disappearing affects the output, the cache key should incorporate that as well. Should there be a way for such tools to get this information somehow? Ideally the paths would only matter if reported diagnostics *would* look at the files, not just "there's a BMI that mentions a source path X" kind of inspection. --Ben
