Exactly. Its a no win, people are going to show up prior to park open. In any scenario, the first ~10,000 people will likely get a boarding pass, the rest won't. If all those people showed up at 6am and were forced to wait outside until 9am open, and you show up at 9am, they are still going to scan in before you and get the slot.
My guess for the next 1-4 weeks (at least) is treat this like an in demand rope drop and get there 60-90 minutes prior to open.
