I want the url bar. Making drastic interface changes without giving the user an option to accept them smacks of GNOME-style arsehattery.
Provide me with proof that it was not common for children to see their parents having sex in their single room peasant dwellings pre-1800. Or, frankly, in some third world country right now, where they have similar conditions.
I don't actually believe this. I wouldn't mind betting that pre-industrial civilisation, that children saw this sort of thing all the time - and not just pictures and films, but real life sex. Ie, their parents.
Privacy in homes is a modern thing. I bet the children saw sex regularly and didn't think anything of it at all. They probably grew up with far more well-adjusted attitudes towards it than people in modern societies do.
