So, one of Canonical's over-reaching goals is "convergence". This means that we are going to write one app that runs on the phone, and on the desktop, and on the TV, (and maybe even on servers if that makes sense, but probably not for friends), and there is going to be a consistent, unified experience.
Currently, as you've noticed, the work on unifying these experiences is incomplete. This doesn't mean that Friends-app doesn't have a place on the desktop. Friends just happens to be the first of many applications you're going to start seeing on the desktop, that are using Qml and look like phone apps.
In the event that you don't have a mouse wheel, you can still scroll with a mouse by clicking and dragging on the messages, similar to how you might finger-flick to scroll on a phone.
In any case, this is not a bug in friends; we are using the ubuntu sdk as it was provided to us, so if any changes to the behavior of scrollbars are necessary, that would not be something that we have the ability to change in friends (and even if it were, it would be inappropriate because all the other Qml apps that are coming wouldn't benefit from the fix).
