This argument would be valid if libalsa would be part of the kernel
and would be shipped with the kernel. But it isn't. libalsa and
the kernel are two very different entities. It is possible (and is done)
to update either of those independently. Thus the two APIs are never
100% in sync.
While the internal MPlayer APIs are only used within MPlayer.
No other application uses them and when we change those internal
APIs we change not only the API provider, but also the user,
thus the whole system is always fully in sync.
I hope you can see the difference and the cause of for a few
very nice and hard to find bugs.
