There was a problem hiding this comment.
Thanks, it's great to see this material start to move at last.
One final remark about my inline comments is that I have used (i : ι) → κ i rather than Π i, κ i since there was a mixture of notation in the file. Either is fine (though the former is what the delaborator uses so you'll see that in the infoview).
Please apply the suggestions and then feel free to merge!

…DirectSum` (#32450) Adds `fromDirectSumEquiv` as an analog for `fromDFinsuppEquiv` specifically for `DirectSum`. This map combines a collection of `MultilinearMap`s into a single `MultilinearMap` on the `DirectSum`.
