Whether or not precompiled headers lead to faster builds is besides the point, because they increase coupling.
The point of good physical design is to reduce coupling. Reduced coupling has many benefits beyond its effect on build times, in fact it often leads to slower “full rebuilds”. Also, good physical design sometimes requires compromises with logical design, type safety, or even performance.
The problem is that bad physical design has no measurable effects on anything until it’s too late. Once it becomes a problem, reducing physical coupling is very difficult. Boost with its header only nature is beyond that point, IMO.
