Great that C++ compiler teams are working on reducing C++ compile time. The next great feature I think would be a game changer is caching the result of compilation (templates and binary code). A fine grained cache acting at the level of a line (or a function if it's too hard) would save an incredible amount of time to C++ devs, while also simplifying build systems. This would also stop engineers from losing days trying to speedup their build.
