The GPL doesn't mention dependencies or dynamic linking or anything like
that - it mentions derived works. If you want to know whether a module
is a derived work of the core code or not, you're likely to need to
consult a lawyer (though the FSF will give you their opinion if you ask

That depends entirely on what you want the license to cover. It's
difficult for you to produce something that will cover things that
aren't derived works and still have it considered an open source
license. OSD 9 could be argued to prohibit it.
