Maybe not a necessity but would be nice to have.
Seems to me that it is not up to the CEON module to add the tags, but instead should be a function of ZC that just happens to be supported or continued by the CEON module. Didn't find a reference to hreflang in zc 1.5.3 so would say that it is not an issue with CEON URI...
