With open-source projects, realistically there is no shortage of alarm sounding, and there is a shortage of alarm fixing, consequently if you really care about this being fixed you have to volunteer to go fix it.

Open source projects tend to be (and Rust certainly is) a showupocracy. Shit gets done when people that care about that shit does it. This means that important stuff that everyone agrees is important but not important enough for me to do, doesn't get done. And that some things end up being 80% solutions that scratch the itch of the person driving a project and progress stalls beyond that.
