Thanks to Dave and Eric for their replies. I'm moving the feature discussion to a higher level (pmount) and I've opened a blueprint on it[1] with more words on why I think it's a problem[2]. This means that I'm leaving this thread and closing it with this mail. I would like to thank everybody who replied and read this, for their help.
