If I'm understanding correctly what can be achieved now by `arr[rr, cc]`
would have to be modified to use `arr.vindex[rr, cc]`, which is a very
large change in behaviour. I suspect that there a lot of situations out
there which use `arr[idxs]` where `idxs` can mean one of a range of things
depending on the code path followed. If any of those change, or a mix of
nomenclatures are required to access the different cases, then havoc will
probably ensue.
