I'm not sure whether this is necessary. That would assume that the
application's encodings are "better" in some sense. While I'm pretty
certain that the iconv codecs are faster than any pure Python codec, I
wouldn't claim that it was better in all respects. Any application
that wants a specific codec should use the API of this codec.

Actually, there is no need for either the core nor the application to
add any aliases. The .pth approach works fine, AFAICT, and is
completely transparent.
