POC - Use correct options on re-init

[adinauer]

:scroll: Description

On multi init we now only do the bare minimum with the new options. Since the new options might not be used, defer init of certain things until we know whether the new options are actually being used (replaced on global scope).

We can build on top of this to control re-init behaviour once we've decided on which route we want to go there.
