Question: when git clone depth override is empty

Lines 825 to 832 in 3fbfde2

	private Integer generateStartBuildGitCloneDepthOverride() {
	String depth = getParameterized(gitCloneDepthOverride);
	if(depth.isEmpty() || depth.equals("Full")) {
	return 0;
	}
	return Integer.parseInt(depth);
	}

Why is the plugin using 0 as override when the input value is empty? Doesn't it make more sense to use the pipeline default setting?
