I agree with TheBoost.
Yoda: A Jedi must have the deepest commitment, the most serious mind.
The only thing it really conflicts with is the EU.
George made the retcon in an attempt to appease EU fans and stupid people asking, "Where do baby Jedi come from if they never fuck?".
The thing that surprised me was how intertwined the Jedi and Republic were in the prequels. I always expected the Jedi to be a separate organization that was called upon whenever there was trouble, sort of like the Justice League.
Furthermore, the movies barely did anything to define the relationship between the Jedi and the Republic. Why, for instance, did the chancellor have to send the jedi to the Naboo blockade in secrecy. Would the senate have normally had vote on sending the Jedi?
