It does exist, though I believe what it contains is a subset of rpmfusion-nonfree.
For example, on my fresh VM install of F44 KDE, here’s an excerpt of the repos that Discover offers me:
I believe the reason it exists is precisely because we offer it to users on initial setup - whereas it’s deemed unacceptable to offer the whole of RPMFusion at that point because of the patent issues.
A downside of this separate repo (and especially of the corresponding Steam one) is that they don’t provide Appstream metadata, so they don’t make the apps they contain properly discover[1]able in the software stores. See for example this recent thread.
