Because: a) Unlike regular software updates, testing on one CPU model/stepping doesn't test on any other CPU model/stepping; and b) if the updates does regress, unlike most other updates this may render systems unbootable, meaning that fixing any regression isn't as simple as just releasing another update. Thanks for the testing so far everyone.
