 creating it is to provide a manageable way to turn a pre-existing design
 into a parallel one, in a step-by-step incremental fashion, allowing
 the implementor to focus on adding hardware where it is needed and necessary.
+The primary target is for mobile-class 3D GPUs and VPUs, with secondary
+goals being to reduce executable size and reduce context-switch latency.
 
 Critically: **No new instructions are added**.  The parallelism (if any
 is implemented) is implicitly added by tagging *standard* scalar registers
