Is there a reason to prefer /usr/bin/yum-deprecated over /usr/bin/yum?

[praiskup]

I happened to have both yum (because 1minutetip, because ... whatever), and dnf-yum providing /usr/bin/yum. The mock -r epel-6-x86_64 --install ... command failed for me, because I had a broken python3-urlgrabber package. When I removed yum, mock started using the dnf-yum and that doesn't use urlgrabber anymore....

Could we prefer /usr/bin/yum when both yum and yum-deprecated are available?

It is, since the final rpm transaction is more likely to be the same as on the corresponding EL system (dnf can calculate the transaction differently, at least in theory).
