Right. As I said: the *shortcuts* are meant for internal use
only. External code should not rely on them, but can, of course,
use those canonical names as well.

Note that these shortcut bypass the codec registry logic. Codec
search functions cannot redirect these shortcuts to their
own implementations, so we have to be careful about adding more
such shortcuts.
