Good questions, but as I have never attempted to export classes with inline
methods or have global instances of classes in a DLL in my own non-Boost
work, Boost implementors will have to answer you on these items.

I admit that I have stayed away from "inline" in my career, and no doubt I
will soon be castigated by all those who will tell me why "inline" speeds up
code execution.

As for global objects, like many C++ programmers I use them as little as
necessary, and would never think to export a global object itself as opposed
to class definitions and their member functions.
