If you would like to have a hand in developing Haiku, please step up and start submitting patches. The process is pretty clear.
Community feedback on features and design decisions is helpful (and needed!). See Sending data to 3rd party (regarding Gerrit #1875) for a good example of this.
Community feedback to developers (working for free) telling them how to develop (while you are not helping develop) is not as useful nor wanted.
I personally value X512’s feedback on the way things are.
I don’t value external perspectives as much.
