It doesn't modify DEPEND by itself, ebuild have to call unpack_update_depend on their own for that, as automatic updates are problematic when you have to take indirect and multiple inheritance of eclasses into account. As automatic updates aren't implemented there is also no need for a RESTRICT setting or similar, and also no requirements on the order of SRC_URI/RESTRICT/inherit. The eclass also contains it's own implementation of unpack (renamed to unpack2) and src_unpack so the logic which tools/packages are used for unpacking can be maintained in a single place instead of being splitted between the package manager and the tree. If someone wants to use it I can add it on the tree (after the normal review process and being better tested), but I'll only be doing it when there is an actual demand for it (no point in adding an eclass that nobody uses). It's still possible to come up with a package-manager-based solution in the future, but for the moment the eclass should help with the immideate problem (though the problem isn't exactly new).
