This means that supporting new languages with CEDET means _extending_
CEDET, and extending CEDET is apparently not possible with the CEDET

Nor is it reflected in the beliefs of the people who state on-list that
since the time CEDET was "included" in Emacs distribution, it has become
inaccurate to state that Emacs does not come with a unified approach to
creating new language modes.
