No, they can't.
Some users use the Boost libs provided by their (Linux) distribution.
They can't just #define BOOST_THREAD_VERSION 2
If I move from boost::thread to std::thread then yes, I'm expecting
some costs moving.
But merely 'upgrading' Boost, which might not require any action from
the developer himself, should not come with such costs.
