Agreed, especially since we're planning on backporting much to 2.6. I
want to draw the line at *dropping* stuff from 2.6 though (or
replacing it, or changing it). 2.6 needs to be *very* compatible with
2.5, in order to lure most users into upgrading to 2.6, which is a
prerequisite for porting to 3.0 eventually.
