To make it clear here is the specific link on the fedora-devel archives
discussing this:

https://lists.fedoraproject.org/archives/list/devel@lists.fedoraproject.org/message/ALJVP7YTSEPC4HNH6JSFMFM6MCUP5HAT/

"Currently we're slated to keep yum as the primary name/command for package
management in RHEL. It may or may not be backed by dnf at some point; we're
still looking at the pros & cons and how to bring better compatibility if
we go down this path."

So my expectation is that RHEL8 will use dnf internally but the interface
will be called yum
