This submodule in turn references another submodule with a URL "outside.com". This is the URL I want to rewrite. Do you think this could be useful to others as well?

How do you distribute new copies of Git to your engineers?
Maybe you could ship them a version which has the "include" line
already builtin as default? So your distributed copy of Git
would not just check the default places for configs, but also
some complied in /net/share/mycompany.gitconfig
