Thanks for the response 
So this suggestion is different due to attaching the incentives to contributors instead of ideas. So in your situation you would submit your professional information and contribution history to a contributor process and the voters would decide if you are going to become a paid contributor for a period of time. If you get selected you’d be able to work on any of the open source initiatives you mentioned that you have been already. Your task as a contributor is to make as much impact as possible. Those that are most performant and effective at doing that will likely be funded in future contributor selection rounds.
This is much easier for voters to handle as top performers don’t change that often so voters can keep selecting them as it’s obvious they are consistently executing to a high standard. For yourself and other contributors it means you can get stable income and can move between ideas much more fluidly based on the needs of the ecosystem.
If you look at all the founding entities across crypto, you’ll be hard pressed to find any of them working internally using an idea funding model where all of there ideas must be selected for each individual to receive any compensation. This would add in massive complexity and remove any stability in working as a cohesive team. No large company operates in this way either - if it was more effective to attach the incentives to ideas then you’d see other examples of this already.
I have some more content around treasury income to release sometime soon but generally speaking I think ecosystems should be able to look after themselves and not be dependent on good will gestures to be maintained and developed in the long term. The most logical way to achieve this means a percentage of transaction fees should be allocated to a treasury that helps with funding the maintenance and improvement of the network. This is what would make an ecosystem self sustainable over the long term. There’s also lots of software built on the network like frameworks, utility libraries etc that don’t need a token, these initiatives are another good candidate to be supported by ecosystem treasury funding.
