There is no "should" here. I let most people decide for themselves
what they prefer.
e.g. You may intend to move to std::thread, that's fine. Others may
choose to continue to use boost::thread and boost::shared_ptr
because they may not want to keep switching between std and boost
for whatever reason(s).
(In some cases, those reasons could be as simple as wanting newer
features in Boost libraries that evolve faster. In other cases,
it might be as simple as their organization updates Boost versions
faster than they migrate to new compiler versions).
As for documenting that there exists a standard version and describing
the differences, sure: I can see the value in that.
