Because of its template magic Boost can create heavy compile-time requirements 
in terms of memory usage. That's probably more significant than the size of 
the sources.

Would it be an option to copy the share_ptr to our sources and hide it behind 
a typedef? This would make it look consistent and it would prevent that Boost 
stuff we don't want sneaks into our code just because the dependency already 
is there.

That makes sense.
