I've never understood why there isn't a dev framework to allow users to "unlock" certain FOSS features. E.g., you scroll through a list of already implemented/tested features that are stored somewhere that isn't publicly accessible, perhaps with demo videos if it's UI stuff. Each one is priced. If someone pays the price, then the source for the feature gets automerged (if possible) and ships with the next version of the software. If it's served by the same maintainers who run the project then there's no trust issues with it.
