I am somewhat suspicious about the idea too, although for different reasons. Notably, most things that run routing protocol these days use ethernet plugs for them (+- some wireless ad-hoc people). Even if I have ‘modern cheapo router’ on both ends of a powerline bridge, odds are, it is just using ethernet plug. So link type autodetection is out of the window, and if I manually need to specify that this ethernet is really powerline, I might as well configure the routing protocol, and I find both ideas non-appealing.
