This seems very "project focused" rather than developer focused, many people contribute to open source projects but don't necessarily represent their project or don't wish to take away funding from those projects, but could still desperately use funding for their work.
I have a personal donation page but I'm struggling to get and retain funding, especially monthly donations, which would make it easier to spend time on the projects I contribute to (either my time highlighting the work of others on social media, or writing code).
