Who says that it names a device? It names interfaces.
There are good reasons to have names for ifas, and I see no really good
convincing reasons not to put these names into the interface name space.
(in addition it'll save a lot of people a lot of grief) 
When you're proposing a change that breaks thousands of configuration you
need a really good reason for it, and so far I cannot see one. It would 
be different if the older way needed lots of hard to maintain fragile code in 
the kernel, but that's really not the case.
