I would love a bounty system built in to GitHub. If I find an issue in an open source project, I should be able to offer up to whatever amount of money for the maintainer to fix it.
Assuming said maintainer accepts it, they'd be obligated to at least try and fix the issue. Issue. If the issues insurmountable, then maybe give me half my money back.
When someone opens an issue on your open source project, there's no way to tell if it's some 19-year-old trying to write her first script or a 38-year-old FAANG engineer who doesn't want to do their own job.
