This comes with several benefits:

* dependencies do not leak into the compile include roots and link libraries of consumers, so they can never accidentally depend on a transitive dependency
* faster compilation thanks to the reduced include roots and link libraries
* fewer recompilations when implementation dependencies change since the consumer would not need to be recompiled
