Reading an external resource from the subsystem parsing doesn't feel right
to me. Is the goal to move away from the keycloak-server.json to using the
management model?

If that is the goal then a better solution might be to have some sort of
migration operation that would read the file and create the subsystem
model. Then after that the keycloak-server.json is ignored and the *.xml
file will be used.

A write will be triggered if you make a change to the management model.

Not really an answer, but I hope there is not a way to trigger a write :)
