The fact that `VL` is dynamic and can be set to any value at runtime based
on program conditions and behaviour means very specifically that
`scalar identity behaviour` is **not** a redundant encoding. If the
-only means by which VL cold be set was by way of static-compiled
+only means by which VL could be set was by way of static-compiled
immediates then this assertion would be false. VL should not
be confused with MAXVL when understanding this key aspect of SimpleV.
binary compatibility may be achieved with a PCR bit (Program Compatibility
Register). Further discussion is out of scope for this version of SVP64.
+Additionally, a future variant of SVP64 will be applied to the Scalar
+(Quad-precision and 128-bit) VSX instructions. Element-width overrides
+are an opportunity to expand the Power ISA to 256-bit, 512-bit and
+1024-bit operations.
