I think this should go in the ref guide. If your product depends on this behaviour, you want reassurance that it isn't going to change in the next release. Not everyone will go looking through the javadoc to see if this is implied.
Typically it'll either be something like "are always returned in insertion order" or "are currently returned in insertion order, but your code shouldn't rely on this behaviour because it can change in future releases". That's usually sufficient to make an informed decision on how to handle returned values. If it's different for docValues, that's even more reason to state it clearly in the ref guide to avoid confusion.
