AFAIK, it is discussed these days whether weak dependencies can be used to
express package preferences:
https://fedoraproject.org/wiki/PackagingDrafts/WeakDependencies IIRC,

Fedora Code of Conduct:

Soft/weak dependencies are allowed, according to FESCo
<
https://fedorahosted.org/fesco/ticket/1203#comment:6>. The main problem

how do we ensure the "right" one is picked?
