Frontier sure is a very capable studio that pushed the limits of what we thought a studio could do in many areas, but it faces no ordinary challenge either. You might think they're gods, and they better be, because we need a miracle right now.
And just like gods, they remain silent. We don't know what they're really doing, they could simply tell us "Yes, all the things planned have long been completed and will be available at release, and your beta version is way behind our in-house build" to solve things, but they won't do it for some mysterious reason only known to them. This has people worry even more, and you can't really blame them.
