I am not sure I like using the term submodule though, it sort of imply
it is part of something, and thus that something have the properties of
the part, hence we do not get rid of the dependency.

Why not just call them separate components, or modules or something
else. They just happen to live in the repository of the library they
can add features to if they are used.
