They probably don’t want to go beyond the standard. It could lead to compatibility and support headaches and accusations of “embrace extend extinguish” later. Not sure but I seem to recall the ARM licensing terms discouraging this.

Too late, they have a number of proprietary extensions already.

  But those don’t conflict with the spec. They can be ignored and it’s just an ARM64. An ahead of release implementation of new vector instructions could result in actual incompatibility with official ARM64.
