I don't think animating or borders is a problem, because the location dependent borders should be disabled only when at screen edges, when the location is the real one, and the animation as well should be done only when at screen edge or in panel as well.

If the property ends up being really needed, i can see it working as a direction (instead of location enum), without any setter.
To be usable in applets however, it would still need a plasmoid property, like popupsDirection, wouldn't even be that bad, but for it to work it would need to track the scene position of the applet, thing that seems possible in 5.3 but heavy on cpu
