That doesn't preclude those modules exporting their
functionality in the form of codecs having the standard
codec interface.

There are two independent issues here:

1) Should the functionality be provided in the form
    of a codec? (Yes, that's fine, IMO.)

2) Should all codecs live in a central registry and
    be callable via methods on strings and bytes?
    (I'm not convinced that's the case.)
