That looks like a very solid document.  Does it also apply when 
considering upgrading a package already in the platform to a newer version?

Also, I notice that 
http://haskell.org/haskellwiki/Package_versioning_policy does not 
mention adding new instances, which caused a problem in the past.  I 
would argue that this ought to mandate at least a new A.B.C version, if 
not a new A.B.
