That's an ISA extension. Yes, an optional extension like graphics and general purpose extensions and some embedded chips lacking floating point. Motorola also has a number of extensions in their embedded chips for controlling additional function units and ports. Also, the Altivec ISA should remain consistent, not growing like MMX, et al. I am not even sure if Altivec is an official optional extension to the PowerPC architecture.
