> incremental builds are not _that_ much faster Right now, they aren't. This will change as things improve. Remember, this is just the groundwork to allow incremental compilation to work at all. There are lots of places where the compiler now needs to be updated to use that framework. > build outputs are no longer deterministic functions of just the build inputs (which is useful for example for distributed build systems). You don't have to use incremental compilation if you care about this problem. But you will want to, because it isn't a problem in practice :) There is no reason why distributed build systems couldn't simply be made aware of incremental compilation.
