 following a similar scheme to EXT001 in Power ISA Public v3.1,
-one bit indicates "this is an entire new 32-bit scalar space"
+one bit indicates "this is an entire new 32-bit scalar space".
+although the "penalty" is that any such "escape-sequenced"
+32-bit instructions require a prefix-marker bit, it does effectively
+double the **entirety** of the 32-bit Major Opcode space.
