I think I will need more explanation on this.
I still don't know how could I test WindupProcessor, which should
initialize the graph, while having the graph already initialized.
Is that what the description below would solve?

Create a class for each bootstrap phase you want. Create an ordered
list of the phase classes. Iterate over the list. Emit a CDI event for each phase, and
have anything that needs to execute in that phase observe that event and start. Observe
the built in @Initialized ApplicationContext event to kick off your bootstrap class.
