These without question have to go in EXT0xx. Future extended variants, bringing
even more powerful capabilities, can be followed up later with EXT1xx prefixed
-variants. Examples include adding psvshape in order to support both Inner and
+variants, which is not possible if placed in EXT2xx.

Outer Product Matrix Schedules, by providing the option to directly reverse the
order of the triple loops. Outer is used for standard Matrix Multiply, but Inner
-is required for Warshall Transitive Closure.

+max instruction).
The Management Instructions themselves are all Scalar Operations, so PO1-Prefixing
is perfecly reasonable. SVP64 Management instructions of which there are only
