AFAIK, Nicolai tried to create an API to transfer state and data between
various versions of livepatches. The primary goal is to keep the
callbacks maintainable. They might need to create, update, take over,
or destroy some data structures according to the actual state
of already installed livepatches.
We might discuss it if there is a wider interest into such an API.
