Yeah, the reparenting is currently very manual.

Right.  It's possible - but just pretty gross at the moment, because
you'll have to start making callbacks into the node system, and you have
to worry about which nodes you've locked at what point, and whether
you're holding a read lock or a write lock.

You can look at how I did it for the iradio genre in
rb-iradio-backend.c.   The library will be a bit more complicated
because you have to handle genre/artist/album.

Anyways, this is something that I am working on with the node system
rewrite.
