After the PR has been sitting there for a year or two, trying to decide if it's the same bug can be quite difficult if the submitter didn't know which of a dozen DDB commands to type, or know how to try to extract kernel debug information using gdb. I'm not saying this is a substitute for a full dump, but that in many situations, I would get more rather than less information as a result of what we're talking about. Robert N M Watson
