I think you’ll find that most fridges these days DO come with the connection for the water and ice service... the manual fills are a thing of the past I reckon!
We had MJH provide the tap for us, however we asked them to recess it into the wall cavity, so it wouldn’t take up space. If they won’t do it for you for whatever reason, then ask them to put it in the pantry (if adjoining) and then when you’re ready to move in, run the water pipe for the fridge through the wall.
Very handy and glad we done it!
