But... it shouldn't. People are arguing that a bad abstraction is better than none at all. Badly-implemented abstraction is the same. If you hit code that is duplicated organically a dozen times, you don't make it a baker's dozen. You spend a bit of extra time at least stubbing out the abstraction so future organic duplication can at least share an entry point. Abstractions grow organically too, in well-tended codebases.
