Talk about missing the point. This is an RC release, which is basically identical to the final release (except for some recent examples where final got an updated build) and in any case, the same unpredictable behavior rings true for many final releases just as much as it does for the beta. Installing any IPSW these days is equivalent to playing Russian roulette with your phone, it doesn’t matter what kind of build it is classified as. None of this would even be in question if the trillion dollar tech company’s software wasn’t consistently broken and unusable.
