I really like monorepos. But I find that it's almost never a good idea to hide parts of a source code from developers. And if there's some secret sauce that's so sensitive that only single-digit number of developers in the whole company can access it, then it's probably okay to have a separate repository just for it. Working in environments where different people have partial access to different parts of the code never felt productive to me -- often, the time to figure out who can take on a task and how to grant all the access might take longer than the task itself.
