If you can't say, it means you're not sure if there's a clear win,  
and if thats the case I think you gotta be on the side of not  
removing it under Hippocratic rules.

Yeah.  Or just leave it in. ;-)

Yup, see my mea culpa in my first message to this thread.  I don't  
like needing to take a hard line on these issues, and I gotta admit  
to being extremely sympathetic to wanting to rip out all of this  
stuff in a perfect world, but my first allegiance is to my customers,  
who have completely different goals than the people who want rapid  
change.
