Thanks. I updated the OP. I would say it's a setback in multiple ways. They have to figure out what caused the failure, which means that rocket isn't launching again for some time. That's assuming they even have another booster.
While I agree they've proven the rocket can keep them safe even in the event of a failure, I don't think anyone would want to experience that escape burn personally. Especially when SpaceX is launching things to orbit without any failures. The worst they've had recently was losing boosters on return, but the ascents have been flawless.
If I had the kind of money it takes to go on one of these flights, I'd probably be signed up for a SpaceX flight instead.
