One last nitpick about this structure, because I did not figure it out at
first.

'fallback' is what we known as 'name' in CCF so far.

What do you think about renaming 'fallback' to 'name' and 'name' to something
more obvious, like 'of_name' or 'fw_name' or something else ?

Anyway, with this patch, I should be able to remove a lot of (ugly) code I
have been writting lately. I'll be happy to test it when you have a v2 ready.
