It's unavoidable in a large project unless your build dependencies are down to the method level. Typically library targets don't supply a single method, they supply a file which has a number of methods, and not all of them are used. But even in the case where you don't get dead stripping, you'll still get deferred code motion. And even if you don't get deferred code motion, you'll still get better renaming, because with type analysis, you can know which properties are disjoint from others. At some point the argument gets into the "I don't need a C compiler, because I already write fast, efficient ASM code" territory. If your code base is perfectly gardened, ok, you don't need any compiler tools. The statistically likelihood of that situation remaining stable as your project ages and adds more developers approaches zero IMHO.
