I am not sure that having a subdirectory under core which is licensed 
differently from the rest of the code is good. I imagine a situation 
when one would need a license statement like

   "All of my past & future contributions to LibreOffice may be
    licensed under the MPLv2/LGPLv3+ dual license.

    All my contributions to directory foo may be licensed under the bar
    license.

    All my contributions to directory bar may be licensed ..."

which would become a nightmare. I suppose that if a separate-licensed 
thing is required, then just create a dedicated project, which would be 
external dependency for LibreOffice. Of course, you'd need to get the 
license statements for the existing code (as you discussed).
