On a semi-related front, I'm also interested in lowering the threshold for participation in FOSS projects, but I approached things from the lens of helping potential contributors better grok/intuit the social/organizational structure of a project. To that end, I made small badges that projects can add to their READMEs to indicate, to a rough approximation, what "type" of project they are[0]. The project types are described in a really interesting book called Working in Public: The Making and Maintenance of Open Source Software[1] by Nadia Eghbal.

The entire purpose of these responses is to repel the drive-by contributor who invariably generates clerical work for the full-time maintainer. It's just a sad fact about the nature of this work that it's often done by volunteers who are massively overloaded, and "contributions" are often so minuscule or low quality that they are actually just additional time-demands on already-overworked maintainers.
There is a good book about this: https://www.amazon.com/Working-Public-Making-Maintenance-Sof...
