Hi @KharonoftheStyx Super psyched to hear more from you, as well as to see my brother has joined the dialogue! If I may provide some additional insight:
I had actually thought of the Service Corps while writing LPs (I’ve read a book or two about how Obi-Wan gained Qui-Gonn as a master, and how he might have had to join the Service Corps if he failed). BUT you’ve pointed out something I have overlooked when writing with this in mind. Steward in the Monastic Setting should be a LP requirement for Physician (Metropolis), Tutor (Palace), and should be able to lead into those settings as well. As for Agriculture, just lead from Child Devotee to Farmer in the Fringe. For exploration, Child Devotee can lead to Spacer in the Fringe, then have them ascend the necessary steps to Explorer (even members of the Order have to live their lives).
Remember, a Jedi Peacekeeper is just a Peacekeeper who took the Padawan LP beforehand. Same with Commander and General - the Military Knight LP is a great way to take you part of the way - but you still have to live a little to get there. Remember that every LP you take in BW colors and provides context for every LP that comes after it! 
It’s funny, when I designed this trait I thought that I would fight everlastingly to reinforce it’s implication, and now I realize it’s too limiting…now every Dark Side lifepath is specifically Sith-oriented. I think the trait serves it’s purpose well, but now I’d like to reevaluate its mandatory nature.
As to what Wembley said about no new LPs, there is enough errata in this pdf right now that I wouldn’t mind going back and fixing some things and filling some holes. I must sheepishly admit I’ve already written notes about new LP ideas, but it’s just a matter of focusing on making this hack playable (and character burning is an important part of play!).
