Unleashed Lightning No More?

Currently on the PTR for Patch 5.3, the benefits of Glyph of Unleashed Lighting have been baked into the Elemental spec. This follows Aspect of the Fox being removed and allowing Hunters to cast on the move at all time in Patch 5.1. I hope this change for Elemental goes live, but it makes me wonder whether the rest of the ranged DPS classes/specs will see these changes in future Patches. Could Icy Flows for Mages be next on the chopping block?
