Yes, if you want to put it that way. We want to use a backend that can
supported the desired user experience.
The hawkey stack is groomed to replace yum anyway. All we're asking is
that we can use it early, so we can provide the testing exposure they
need and ensure that hawkey does actually support the things we need.
Without that, there's a very real danger that hawkey/dnf end up
producing a perfect copy of yum (including all of the problems)...
Don't worry, that's not gonna happen. Hawkey has been built on top of libsolv
library that implements a different solver than yum uses. Under no
circumstances will this change. The more likely scenario is that gnome-
software/PackageKit will be forced by the policy to use the old yum which will
make future adoption of dnf much more difficult.
