If you want that, negotiate a contract.
But instead we have these attempts and stopgaps, some of which have had some success here and there. This is something else in that pool making it easier to fund stuff, and if it gains traction than we'll know that it's serving its purpose. I think it has good potential.
I'm thinking about the far more random regular people using random projects that may not be that popular. Like I just did a rough count of the OSS apps on my phone: 60+. Of those there are 5 that I can immediately think of improvements that I'd like. One of them I've actually made improvements to already because it was a dead project that I really like and so had to revive anyway. And I used Claude to work on it as I'm not a mobile dev; been planning to republish but haven't gotten around to it. I won't bother to check my laptop but there's even more there.
Now imagine if I (and others interested in those projects) could contribute to small funding pools for various projects of interest, with the assurance that said funds go to that feature/fix which is of interest or gets refunded. I think that'd result in the general OSS support needle being pushed that much further over time.
If all you’ve got is relative pocket change they probably aren’t going to agree but if you put real money behind it and it doesn’t go against their vision of the project then most people would be willing to accept actual contracting work to expand their project.
