Got it - I still think it would be good to use stricter names. For somebody focusing on SME, "tile" will normally mean "SME virtual tile". So all good. However, for people more used to Linalg level of abstractions, "tile" is just a slice of the iteration space. I just think that the term is a bit ambiguous and overloaded.

Another option that could help disambiguate:
* `ZATile` to represent e.g. `vector<[8]x[8]xi32>`, and 
* `ZASubTile` for things like `vector<[4]x[4]xi32>`.

These would be different for different element types.
