I should have been more specific.  I was referring to:

./libs/serialization/src/polymorphic_iarchive.cpp
./libs/serialization/src/polymorphic_oarchive.cpp

I'll query the dev list on the pros/cons of explicit instantiations with  
seperate template .ipp files vs. header only template files, right now I'm  
leaning against the former.  If there is a general consensus that explicit  
instantiations are not needed, then I'll open a trak item to do away with  
them in the serialization/archive libraries and add what researched  
results I've come up with.
