"Pretty common back in the day from what I read. Very low chance of revolt."

Yes, but then you have to build up everything yourself. So to have a working province that can be milked soon, quite often local structures were also left intact. Important is to crush their culture/religion if you want to crush their spirit to revolt. Thats why the romans killed the druids of the gaulls and took away children of the nobles to make little romans out of them.
