Agreed, this approach makes sense.

I chose this term because the same term is used in CGAL. I thought
what they call "kernel" was precisely the concepts part of the
library, but maybe I'm wrong, I don't know much that library.

For sure it would be better. And the fact of trying to "extract" a
kernel from both library is much less frustrating than forcing one to
give up the core of his work. We don't throw anything away, we rather
take the "quintessence" of each one.
