I feel like you, and in another environment entirely, I found it's useful to make the working implementation in secret, and open the ticket as if it's a new idea and steer the conversation towards your implementation. People like to feel like things are their ideas, so if you can guide them suggest the idea to you, it'll definitely get accepted. Personally I don't bother contributing unless I'm getting paid - otherwise I have no incentive to deal with the people bs.
