Many symbols in eieio are the names given by CLOS, like 
initialize-instance, make-instance, with-slots, and call-next-method. 
Other names like oref/oset were meant to fill gaps where Emacs couldn't 
do it the clos way.  If Emacs is to have a good way to do some basic OO 
programming, it seems to me that the names would match up with other 
core functions that crowd the core namespace, and it would seem poor to 
fill your oo code with a bunch of unnecessarily long names.

That said, there are certainly plenty that could be removed, and I would 
not be sad to see them go... like 'this' and a few of the class-* and 
object-* functions.  Some already have eieio-* equivalents, but I didn't 
finish that.
