Reconsider information for the application of smart pointers

I would appreciate further clarification around information like the following.
* https://github.com/google/styleguide/blob/5651966e0275572a9956199418d89c9ccc7b2b1a/cppguide.html#L969
…
Smart pointers (unique_ptr, shared_ptr): smart pointers execute cleanup during destruction and are therefore forbidden.

:crystal_ball: Should a conflict be resolved for such an advice?
