Another side note on this: Just because someone puts a bounty on an issue, it doesn’t mean that it is going to be accepted by the project. It will always stay the decision of the component maintainers, whether a contribution is ok or not.
To sum it up: As mentioned above, I too had some doubts about this mechanism, but I would like to ask you all to just wait and see whether there is any noticeable impact. If you see concrete situations where it actually causes damage to the project, please raise this at any time and we can discuss appropriate actions.
