Wrong, Heat Blast/Energy Blast is also still off of the GCD.
I'm not sure this design philosophy even exists, it appears to me like players are inferring information from a couple of examples to create a concept for which they want to be a design principle so they can justify a change to another ability. Here is some cited reasons on why they actually changed a couple of the aforementioned abilities in this thread.

So both their actions and words suggest against this concept of flat out removing non GCD respecting based abilities existing. There is and was no change as has been suggested.
Indeed.
