Well, you're not alone there.

I am. I just wanted to suggest that it shouldn't be a settings file but
something like a module file.

So in this case foo-bar-1.0 could actually be a virtual module, but as
it is specified under dependencyManagement, it wouldn't pull in the
dependencies but just override the versions.

OK, will do.
