In my workplace, there's an obsession with line-by-line code reuse. And the client uses a tool that uses LoC as measure of code re-usability. Often for two modules, if the logic is same _**as of now**_, those modules call the same method. Which reduces no. of lines, but seems like a long-term manageability disaster. Are my concerns valid? Or I'm missing something here? Not a duplicate of [this question][1], I am worried about plain LoC based measure. I understand breaking it down to smaller component, but it's not that.
