I think that's an important point.  For some related opinion, see:

"worse-is-better, even in its strawman form, has better survival
characteristics than the-right-thing"
  -- http://www.jwz.org/doc/worse-is-better.html

My point being that we have some knobs to play with here, and that winding 
them fully to one end of the scale is likely to result in something that 
few want to use, or can be bothered to learn.
