True. I would be fine with removing the plugin requirement. Or
changing it such that it states that plugins can only be loaded if
it's done in a manner that ensures that all other requirements are
still fulfilled. Or just dealing with this once there actually are
plugins and plugin APIs which could be loaded while still fulfilling
the other requirements.
