There's information in docs (https://vuejs.org/guide/essentials/template-refs.html#refs-inside-v-for) that the order of the elements of an array ref is not guaranteed.

It may restrain some developers from using <foo v-for="..." ref="someRef"> and make them search for another solution resulting in the correct order. However if the statement is valid only for very specific scenarios there should be some example(s) so that developers know whether their usecase would provide the correct order of elements or not.

If this is something that was just copied from Vue 2 and is not relevant any longer then it should be removed
