I don't think anyone would ever say they want "id, id, id"? They would say they want "customer_id, order_id, item_id" or some such. You would then probably say, "we just use 'id' for the id of every item..." but many places that I've worked actually explicitly didn't do that for essentially this reason. Natural joins on "foo_id" "just work" if you don't give every table the same "id" column.

That is what the syntax allow. And is the user that need to "patch" the meaning using other things like alias, renames or hopefully, proper names for fields (by the way "id, id, id" happens a lot in the wild!)

Is like "to control mutation I only need to append "mut" to the name!

Current SELECT syntax does allow one to "SELECT user.id as user_id, product.id as product_id..." which can then even autocomplete the FROM for you from your query "declaration" (a-la function declaration, in particular its return type).
