Possibly. At the end of the day, the client code must instantiate all
needed classes, so it's likely that it includes everything.
However, the advantage is in compilation times for the library. On the
one hand, the overall time can decrease as each source file might
include less headers. On the other hand, and more importantly,
incremental compilations are faster since changing a header file might
cause less source files to be recompiled.

This said, I'd love to see experimental data on compilation times before
and after the changes...

Sure. Any ideas?
