As a seller, this is a very welcome idea! However, I would like to highlight a point that is often a source of misunderstandings with buyers, especially considering the following sentence:
Share the asset (directly, via a private repository or in the Project) with your collaborators that are working on the Project with you
This is misleading for code plugins, which are instead licensed per-seat, as per clause 2.e of the Fab EULA:
2.e Plugins. Code plugins that are being offered on the Epic Marketplace, including Unreal Engine Plugins and Unity Plugins (“Plugins”), are offered to you on a per-seat basis and may only be used by the number of users that you have purchased licenses for.
It would be extremely helpful, both for sellers and buyers, to add an explicit note about this.
