That document, as the name implies, explains the current differences in 
*cli* behavior to yum, as in "things that might cause surprises for 
long-time yum users". Dnf doesn't exist to tinker with some cli 
differences just for the heck of it, the main reasons and goals have to 
do with the underlying depsolving engine and API, see eg


This and the other thread on fedora-users does make it clear that 
background and goals of dnf needs to be more clearly communicated though.
