It's an interface issue.

RMS is quite persuasive on why the optional BUFFER arguments are a Bad
Idea.  They're a blight on the source code, inconsistent in the face
of needing to add further parameters, and a needless inconsistency
between XEmacs and Emacs.  When I last checked, we may have had a call 
or two in 640,000 source lines of Lisp that used it, but we might not
have.  There's also a lot of pain[1] involved in portably dealing with
functions that take a different number of parameters.


Footnotes: 
[1]  The thought just struck me.  Once #- and #+ get ported, can we do 
something like this?
