I think that's the case, yes.

Well, if you wrote a patch that uses a closed-source database library
to store git objects in, how would that benefit the community even if
you published the patch?

You could ofcourse fork the library, but then you'd have to take care
of namespace conflicts and such things. The fork would naturally have
to be licensed GPL + gcc-exception too, since it's a derivative work.
