Speaking as a Mozilla developer - sure it does! We release every 6 weeks, and don't hold new releases for features. In the past, we ran into far too many cases where new feature X that wasn't ready held up a release for all the other features that were ready. Now, we'll just remove or disable that new feature and ship.

OSX and Ubuntu release like clockwork. People appreciate consistency.

Two things: 1) OS X releases at the whim of Apple, not "like clockwork." 2) Every 6 weeks is "like clockwork"! :)
