This is a tracking bug for a change in how fedora-release defines the $releasever variable value which is then used by package managers. By changing package provides, it's possible to convince DNF to replace $releasever by a "rawhide" string instead of the usual numerical value. This change would simplify several areas, mainly related to configuring system repositories or maintaining third-party repos.
This change is discussed in more detail in the following releng ticket (it's the Proposed solution 1):

This bug serves the purpose of tracking issues in other tools that could be incompatible with this change and tracking progress of fixing/adjusting them.
