I guess that's not impossible, but it seems to reinvent git submodules without the tool support I'd want, and I think explicitly depending on our fork of their library would be clearer and safer.

I complete agree. To temper my comment, I've seen plenty of bad examples of copying dependencies, bundling old un-updated versions, with undocumented changes. In such case, it's true that copying leads to a worse kind of dependency.
