Not really, just been a while. Snow leopard was named the way it was because it was literally an entire release dedicated to bug fixes and stability improvements from leopard (and yes, its rollout was rough, but it became a massive improvement over leopard after those gm release issues were ironed out)
They need to do that again, not just a temp freeze but an entire release cycle where feature work is deprioritized and focus is on stability and bugs
Snow Leopard was loaded with new features. OpenCL, Grand Central Dispatch, these were not 'tiny things' but major core upgrades.
