So, to be clear, it is not now nor was it ever my intent to try to keep lightsabers out of the hands of Jedi, especially to the ones for whom the 'saber is an important part of their character concept. Not giving them out as guaranteed starting gear simply encourages players to evaluate all their character options as a force user.
It sounds like FFG did a great job of making 'sabers accessible early, and even gave them a good opportunity for progression using their excellent mod system, and have given the GMs the tools they need to throttle that progression to meet the needs of their campaign.
I look forward to getting my hands on a copy of the book so I can fully appreciate how things work.
