You seem to have a lot of expectations & be uninterested in the underlying technology. Open source is about more than "things work as advertised;" it's also about picking good tech & insuring we have open paths to the future we can advance on.
Your belief that "Needs to be a lot further along," applies to who? Yourself? Everyone? This seems like a great pitch to me, at a great time to get onboard.
I definitely see it as a feature, but I don't choose software solely based on this.
It's also likely that if you're using rust you care about performance and have thought about it while building your application, this is also a feature.
What's fascinating to me is everyone who says written in Rust isn't a feature. It definitely is, and it's going to keep eating C and C++'s lunch in new areas every year.
