Unnecessarily aggressive response from you given that you are addressing positions I never actually took. Of course the maintainer is entitled to exercise personal judgement about what gets included. When did I say anything othrwise?
What I am saying is that, as a user, it is frustrating to spend time putting together submissions and then hear absolutely nothing back. I am not demanding special treatment, just a basic acknowledgement or a brief explanation when something is rejected. Expecting that level of courtesy when you interact with a project does not strike me as unreasonable. If that is considered entitlement, then yes, I suppose I do expect basic courtesy from people I engage with.
All I am asking is whether anyone might be interested in building something more community-ish, where decisions do not rest entirely with one individual. If someone creates that, I am happy to support it with my time and contributions. That is the only point I am making.
