I suggest to separate the application from the back ends.
As the backends will have to be updated once in a while (sadly), it is almost impossible to get them stable.
If the application itself does not have to be changed, we could move it to stable.
The application then could have a function to go and look for backend updates and download them.

Also, if the back ends (configuration) is held very basic, other users could easily adjust them to the new service requirements.
This would take a big maintaining load from the author and we could respond quicker.
