I like this idea.
The way that we currently deal with things like this is to place a bunch of hidden copies of the components and wrap them in an auto layout so that the container resizes to only the objects that are viewed. Then when we need more rows, tabs, cards, etc. we go to the layers panel and just unhide more.
*Note this approach is still a little problematic because it doesn’t let you rearrange the order like you can do in a detached component. So our work around for this that sometimes works is that when we start by showing/hiding every other copy. It would be nice if we could override auto layout object order without detaching the components.
Here is an example of out Tabs Bar:
