I kinda disagree with putting Wine and Playonlinux to the distro. I mean it's rather useless for most of the people and only some would use it. ia32libs however are used by nearly everyone if not everyone.
Well, except if WineHQ and Playonlinux were optional and you could check/uncheck them during installation, then it wouldn't bother me. They just shouldn't be put in the installation process by default.
