Comment(by igloo):

 Note that this would only solve part of the problem. If something is
 defined inside a module and not exported, then you're still out of luck.

 I think adding the flag is a bad idea. You can always modify the package
 locally to expose the modules you need, and the right global solution is
 to ask the maintainer of the other package to expose a `.Internals`
 module.
