Hi

Of course, dnf repoquery for packages that depend on yum/yum-utils yielded quite a few more packages.  So I have filed RFE's against all of them and added them to the tracker and fixed the wiki references etc just to complete this process

It is possible, even likely that some packages just assumed yum/yum-utils would always be there and didn't add an explicitly dependency.  Since some base tools including mock still depend on yum by default in rawhide, we wouldn't know about those hidden issues till those are ported over/dependency on yum is dropped.
