Suggest to loosen the dependency on nameko

[Agnes-U]

Hi, your project ditc-products(commit id: 456ab2e) requires "nameko==2.11.0" in its dependency. After analyzing the source code, we found that the following versions of nameko can also be suitable, i.e., nameko 2.12.0, since all functions that you directly (6 APIs: nameko.standalone.events.event_dispatcher, nameko.testing.services.entrypoint_waiter, nameko.extensions.Entrypoint.decorator, nameko.extensions.DependencyProvider.init, nameko.extensions.Entrypoint.decorator, nameko.testing.services.entrypoint_hook) or indirectly (propagate to 12 nameko's internal APIs and 17 outsider APIs) used from the package have not been changed in these versions, thus not affecting your usage.

Therefore, we believe that it is quite safe to loose your dependency on nameko from "nameko==2.11.0" to "nameko>=2.11.0,<=2.12.0". This will improve the applicability of ditc-products and reduce the possibility of any further dependency conflict with other projects.

May I pull a request to further loosen the dependency on nameko?

By the way, could you please tell us whether such an automatic tool for dependency analysis may be potentially helpful for maintaining dependencies easier during your development?
