There are many cases, where we have short helper functions or even classes (e.g. enums) that should be available for all Services by an "import" statement.
It's partly possible to implement this kind of functions as Ressources, but ...
- These need to be implemented in Java, which makes the implementation more complicate
- On Runtime we need to marshal all the parameters and return values
Storing these little helpers in a central file could enable easy functionality like enums, reduce error sources.
