How come no one seems to pay attention that Austria is a bit of a slut?

Let’s take a look,

You have the popular Hungary x Austria

Then you have the also popular Prussia x Austria

Then the less popular France x Austria

Then of course Germany x Austria

After that the Hapsburg Pairing, aka Spain x Austria

And then of course, you have Swiss x Austria

Keep in mind, these are all historically canon and might as well be Hetalia canon too. But seriously! I can’t even-he’s such a slut…why isn’t this played on more in things…am I just looking in the wrong spots?!
