I also rarely use them, but sometimes pointers (via virtual methods and factories) can reduce compile times a lot for components with a stable API but high complexity and churn of the internals. Do you have another way to handle that?

I tend to rely on member unique_ptr for such concerns. At top level, you still don't see any pointers. Of course at machine level the code is absolutely lousy with pointers, likewise at the next level up, but the pointers you can't see because they are buried in libraries cannot generate bugs.
