Currently, it is difficult to find the source of a quirk. Blame doesn't always give the source of the issue (specifically after code rewriting). It makes it hard for engineers who want to remove a quirk to go back in the history and find the origin and/or steps to reproduce the issue. The intent is to document with comments in the source code.
