I wouldn't pay a lot, but I would definitely pay.

like a buck or two a month billed anually I would buy without hesitation if I believed it had real value.

I usually search github directly now for these things, and it works decently well; either finding the code in the repo to which it belongs or better yet, an issue addressed by the developer.

As the sibling said I would probably also pay a small amount. However, I could also see that corporate customers might by this.
