For what it's worth, Ubuntu Tweak -- a popular tool that exposes some gconf options in a GUI and that, I would guess, quite a high proportion of the kind Ubuntu user who argues over this sort of thing on Launchpad already runs -- has already released a version that lets you change window button order.
This is a situation that Canonical's probably delighted with -- they don't have to expose a new configuration option by default (Canonical seems to share Gnome's point of view regarding configuration options), but, for people who want to have the control in a pretty GUI, the tool isn't far away. Similar to Microsoft's stance on TweakUI.
