Still WIP...

There are many ways to solve this.

1. enhance replaceGlobals to be able to change the dependencies dynamically after the replacement. But changing this rather static logic requires quite some thoughts
2. Use addMissingDependencies with custom finder, replacer and extender (dynamic dependency decision in replacer).
3. Use addMissingDependencies with custom finder, replacer and extender (dynamic dependency decision in replacer, config passed then to extender).
4. Use addMissingDependencies with custom finder, replacer and extender (dynamic dependency decision in finder, specific replacer for each decision with extender).
