I intend to merge this next Wednesday EU morning if I get enough approvals by then

I am OOO, but please check doc.go and all comments to the funcs/contracts. I remember some being about only one instance, etc.

I looked through the receiver package and didn't see anything nefarious. I also grepped the repository for "instance", but nothing popped up. No TODO showed up either.

I could not find anything specific to instances in the docs, but I did open this small PR to move error handling documentation to the consumererror package: #12610 (Edit: merged)
