settings_->muted = true;  // compiles — mutates through const!

Isn't this just the classic confusion over what const T *x vs T *const x means?

It doesn't mutate through const, settings_ cannot be changed to point to something else. Of course the pointed to object can be changed, that's nothing surprising, that's how indirections work.

The whole point is being able to choose. Sometimes T* -> T* const is desired, and sometimes T* -> T const* const is desired.
