Actually, I don't. I was just pointing out the generic risk of fixing 
something that isn't broken by breaking something that works. There's a 
lot of conservatism in R where things don't get rationalized for similar 
reasons. For quite a while, bug-for-bug compatibility with S-PLUS v 3.x 
was considered important to allow people to port their packages between 
systems.
