Should mock warn when it is using DNF instead of Yum?

[Miroslav Suchý]

Hi,
right now Mock produces warning when you are using Yum for chroots which are supposed to
use DNF.
Now we have the other situation. There are users which has DNF and does not have Yum any
more.
Should we warn them that they are using DNF instead of YUM?
