The design hasn’t changed since it was AA batteries; it was not designed with the rechargeable battery pack in mind.
The worst you can say really is that it was a lazy upgrade, which is totally valid.
My guess is they didn’t want to redesign the top surface for aesthetics or charitably, perhaps technical reasons to do with the combo touch / click area at the front, and the front is the only place you’d want a port.
