Bundling higher-level concepts in the same dialect as lower-level concepts is something that easily scope creep and leads to intra-dialect lowering: this makes a bunch of things less natural, in particular forming a simple mental model around a dialect (and its canonicalization).

On the high-level op side, I was only thinking of adding `read`, `write` and `make_offsets` (a helper to create int offsets from strides and indices `make_offsets [%i0, %i1][%stride0, %stride1] : tensor<3x3xi32>`). I originally didn't think of this multi-level concepts as an issue, as the `vector`,  `memref` and other dialect do the same.

A new dialect could be created, but it would only contain those 3 ops.
