To answer the ecosystem question... if I were an EL shop that had

I had to rewrite all of my scripts and retrain my muscle memory to
call a new command that had similar semantics and compatibility, I'd
be pretty annoyed. Having dnf in CentOS 7 is a way to help users that
use both Fedora and EL avoid that problem, which is good.
To tie two recent devel list threads, this is a perfect use case for a
~/bin being first in PATH: a ~/bin/yum -> /bin/dnf symlink for those
that don't want to rewrite scripts.
For the record, I was against introducing dnf as a separate command---I
thought (and still think) that it should be yum v.3 (or whatever next
major version was due at that time). Having said that, once the decision
has been made, I just got on with it, even though I use a mix of Fedora
and EL/RHEL so I have to remember which is which and use both yum and
dnf commands.
