Additionally, speaking specifically about boost::shared_ptr here:

1. Reasons some users choose boost::shared_ptr in C++11 and C++14 code:
- shared_ptr<T[]>  (C++17 only)
- local_shared_ptr<T> (Boost only, interoperates with boost::shared_ptr<T>)

2. Reasons some users choose boost::shared_ptr in C++17 code:
- make_shared<T[]> and allocate_shared<T[]> (C++20 only)
- local_shared_ptr<T> (Boost only, interoperates with boost::shared_ptr<T>)

3. Reasons some users choose boost::shared_ptr in C++2a code:
- make_shared<T[]> and allocate_shared<T[]> (until all vendors implement it)
- local_shared_ptr<T> (Boost only, interoperates with boost::shared_ptr<T>)
