I'm exactly like you but my anecdotal evidence shows that we are the minority.
And yep, I'd like to see those same additional features. One-off small payments instead of a recurring donation is a must as well; many can't afford to donate on a regular basis.
I think GitHub is more like the first scenario. You're already getting the content (code) regardless if you pay for support or not.
I'm curious if, in the long term, GitHub will extend this functionality to integrate benefits: faster support, pay for features, even access to repos for various tiers.
