Those features are some of the flagship features of Home.

Drawing over other apps is core to their new messaging UI because it can show up no matter what app you're using.

Running at startup is pretty much required for an always on Messenger type app.

Reading your currently running apps is also required for any type of launcher app I would imagine.

Not Home.

I'd guess it needs to know what apps are running so it can draw over them.

This is getting off-topic but no, that's not how it works. Android handles those chat heads as system-level windows, you don't need to know what's underneath them. The running apps list is for that "Last app" functionality (though I've no idea why reordering is needed).
