 * Preserving the underlying scalar execution dependencies as if the
   for-loop had been expanded as actual scalar instructions
   (termed "preserving Program Order")
+* Specifically designed to be Precise-Interruptible at all times
+  (many Vector ISAs have operations which, due to higher internal
+  accuracy or other complexity, must be effectively atomic for
+  the full Vector operation's duration, adversely affecting interrupt
+  response latency)
 * Augments ("tags") existing instructions, providing Vectorisation
   "context" rather than adding new instructions.
 * Strictly does not interfere with or alter the non-Scalable Power ISA
