lgtm otherwise. Interesting to know that this package may have been modelled after its dotnet equivalent.

It certainly was built on the .Net mode, but, I think we'd all agree, no one praises the .Net model for its simplicity. What is more, it seems like the interface really hides a lot of complexity under the hood; complexity that we just don't have the resources to develop or maintain.

I think I'm happy with the direction we've taken this and I think it gives us room to move forward with the kinds of use-cases that those using this project are encountering.
