Yeah, my suspicious side was thinking about the retainers too. In fact, when we were discussing about the introduction of the extra retainers, I was one of those that said that it would become worse in due time (and I still think that it stinks in many ways, but that's another topic).

I didn't want to mention it here because I honestly want to know why do they keep doing this with some items and not with others. Maybe (and just maybe) there's a weird but legit reason that I can't think of at the moment.
