The good thing about the nightly builds was you didn't have to use them, and people could respond quickly to showstoppers rather than wait for a sprint. There was a quicklook team to catch bugs which stopped nightly builds from release to general dev, and unless you really needed that build ( to test a new API) you didn't install until quality is restored. With fortnightly builds, if that is now what is happening, there will be massive instability every 2 weeks, until the final round of bug fixing cycles. Which can't finish because the OS has to be release at an event.
