Smart contracts are smart enough to allow formation of groups of devs, form a vote and disperse funds. Devs who are directly responsible for maintaining a portion of code can vote if the contributed code solves the issue.
If a trusted group of developers is in charge of dispersing funds, why involve a blockchain/smart contracts at all? You can just donate to the developers, and they can disperse funds according to some predefined terms. The DAO or whatever is exactly that, but with extra steps. In either case, you still have to trust that the people in charge of distributing the funds will do so according to the terms that were agreed upon(fixing bugs or adding features or whatever).
They'd still be trusted in the sense that they decide if a bug was fixed or not, but at least transparency would be achieved. You could independently check exactly where your money went.
