Just a quick thought I really wanted to reiterate.
Out of a pool of 6500 applicants, many of them very deserving of an allocation, odds were always long to get a first 500 allocation. Ford has many constituent groups to satisfy. They are not a boutique manufacturer, and therefore they have dealers, suppliers, fleet customers, retail customers, etc that are all large in number. That was clear from the design of the application, and the categories it contained. That said, the allocation process clearly heavily favored Ford GT owners.
Ford is publicly committed to racing the Ford GT for 4 years. If you believe Ford will produce the road going version for the duration of the race program, or if you spend a couple minutes digging around about speculated production volumes, I believe it would be very fruitful to remain both patient and positive. There is no reason to believe the allocation process would be any different in the future, and that GT owners would not be given priority. The entire process from application to concierge to production is reasonably tailored to a specific type of customer, and changing the process for the future wouldn't make any sense. You could also speculate about the reason why Ford went to the trouble of including both "priority waitlist" and "deferred" notifications, rather than just a single category. I view it as unlikely that attrition will be high enough in the first 500 units to necessitate a substantial waitlist.
The application also underscores that Ford is a media savvy company that pays attention to things like social media and the internet. I certainly understand the level of disappointment despite the long odds, but if you're interest is in obtaining the car, I would just say be pragmatic about this round and don't let it deter your pursuit.
