You know from history that open source has always been shaped far more by the people who showed up with a working implementation compared to writing a comment that says, "I think we should do it like this". This is the "patches speak louder than words" school of thought.
At the same time, you know it's a good idea to confirm beforehand that there's an acknowledgement from upstream of the problem and an agreement about the general approach for the solution, so you don't waste your time.
