As I said on numerous occasions during the last few days, dnf is not a 100% 
drop-in replacement of yum. It aims to be as compatible as possible but within 
reason - one of the important goals of dnf is clean and maintainable design.

As I said, we will have transition layer so using yum in your shell scripts 
will still work for a few more releases. A vast majority of users should not 
experience any inconveniences other than different output on the command 
line.
