Create a kangaru 4 compatibility layer #136
Description
Is your feature request related to a problem? Please describe.
Migrating from kangaru 4 to kangaru 5 is gonna be quite disruptive.
Describe the solution you'd like
I think we can implement a compatibility layer that reimplements kangaru 4 on top of kangaru 5, and let users gradually switch to more kangaru 5 facilities.
Describe alternatives you've considered
Implementing the equivalent of the kangaru 4 container and services, but in practice they do differ in semantics compared to kangaru 5.
