But pipes do not hide ONLY deaths by sanitizer. And by relying on the presence of pipe hiding deaths of git tools to mark the script sanitizer-clean, the TEST_PASSES_SANITIZE_LEAK=true line adds an unnecessary road-block for those who are cleaning up the "git whose crash are hidden by being on the left hand side of the pipe" pattern.
I do not know what to call it if not "breakage".
