Well, this is not going to happen because KEdit is deprecated in itself 
and KTextEditor took over. I was thinking about the way I want to do it 
in the new composer and here's a suggestion:
- have our own editor factory which would yield the following two 
   * our own native editor, (most probably QTextEdit derivative),
   * KTextEditor component, thanks to which 
kvim/kate/hopefully-finally-emacs could be used,

I'm rather reluctant to go with the KTextEditor only solution because 
quite frankly I still don't see any simple KTextEditor component 
suitable for mail composing. So for 3.2 I'd prefer to have a composer 
where the default editor is our own QTextEdit derived widget and 
KTextEditor is optional and then maybe change it the other way round 
after 3.2. 

I mean I like KEdit, because at this point KTextEditor suck for anything 
else than coding. The idea behind KTextEditor is great but we're 
missing some simple editor component. 
If someone took KRichTextEdit and ported it to KTextEditor, that'd be 
the best. The only other complains we can have about KTextEditor are:
- lack of spell checking interface which from what I know should be 
there for 3.2,
- lack of an interface along the lines of QSyntaxHighlighter (and no, 
HighlightingInterface is not even close to QSyntaxHighlighter).
