Similar to the way the other apps (illustrator, photoshop, indesign, after effects) work it would be great if we can place linked artboards into XD.

Linked files/artboards would allow us to update the source file and have the artwork update automatically within XD.

Using CC Libraries doesn't work the same way because libraries can only store individual assets, versus multiple assets that can be stored within an illustrator or photoshop file.

A specific use case might be where a complex set of illustrations made in illustrator/photoshop needs color adjustments by a client.

With CC libraries one would have to update each asset individually. However with linked files we can potentially replace a global color swatch that updates all colors across the different artboards automatically. And then because the file is linked, the XD file will update automatically.

CC libraries is great for simple lightweight assets, but when it comes to importing large complex files, linked files are much easier to work with. (Current workaround is to save out the artboards out as images and place them, which is a pain when it comes to updating them.)
