I few years ago I envisioned exactly this, something like a cross between bugzilla and kickstarter/patreon. I want something fixed/done and want to pay someone a small amount to do it.
Even registered a domain for that. If someone wants to implement this, I would donate the domain (5-letter flattr-like .com/.org).

Are you thinking of the "bounties for specific issues" model? That's something I would specifically want to avoid -- it doesn't provide funding for ongoing "behind the scenes" work, and "feature bounties" often get claimed with horribly bug-ridden code which just barely passes the five minutes people spend to confirm that the bounty should be paid out.
A subscription model has the advantage that if a developer stops producing good code, people can decide to stop funding them.
