Comment 12 for bug 1154176

There are a few reasons why this FFE is important.

1) This code, as mentioned before, was ready before FF but it was put on hold because of an urgent one-off project. It is fairly well tested both by my team in online services and by the unity team.

2) Because this code implements the payment previews it has to be part of unity for any other deliverables (via software center, or PPA) that may need it.

3) This can't be placed in a PPA, because it means putting all of unity in one, and makes a horribly invasive PPA

4) This code is not exposed at all. If we merge only this, and deliver the scopes that support purchasing separately, then this code is simply not visible to the user unless he installs that extra scope, and is effectively disabled.

Delivering in this way, with a FFE for this specific change, gives us the flexibility moving forward, while not endangering the user experience in any way.

Please reconsider.
