My understanding: 

rpm - accepts them as valid and lets you build packages with them. 
yum - ignores them completely
createrepo - adds the info to the metadata
dnf via hawkey - will only use them to break ties if for example two
packages are both possible solutions, but one also is suggests or

not really as far as I know. 

dnf needs to handle these cases, it needs documented, etc.
