Physical coupling is difficult to break, easy to introduce. That is to say
users can not possibly suffer from the many repos because it is trivial to
make a release that bundles everything together.
As for the benefits of breaking up dependencies and splitting libraries
into separate modules, they aren't limited to version control. Reducing
coupling increases the efficiency of development and maintenance work in
general, but that is only visible in very large projects. Which is why it
