"So open discussion is not accepted, changes to the plan are not accepted because they're volunteers and can't accomodate everybody, merge requests are not ideal because they don't have time to review them."

Please avoid this hyperbole. If you actually look, there are plenty of examples of changes being accepted. But you have to play ball with them, like I said you can't just throw code over the wall and you can't just barge in and start trying to pick a fight with someone about the design.

"There's a lot of volunteers in the open source world, yet discussion and ideas flow more easily elsewhere."

If you have advice from those projects on how to improve process to make it easier to do it then please mention that. But otherwise I really don't know what you mean, I have had issues and merge requests ignored/declined in basically every open source project I've ever contributed to.
