I see quite a few projects that get steady development, but have hundreds of open issues, of which most are probably feature requests. In my experience, having the tracker flooded with thoughts for features that it would be nice to have someday, is completely useless and probably actively toxic. Ideas are cheap, while implementers' time is finite. Ideas are best dumped into an ‘inbox’ list―most of them will never surface from there anyway.
As a result, I almost completely stopped posting issues, except for most egregious bugs or when a feature would be a one-line change. As a rule, I now prefer posting pull requests, which of course is a lot harder―but helps keeping things in perspective.
But, somehow both sides end up treating it as a work request, and that causes bad feelings.
