I definitely think project infrastructure should be one of the priorities, because having good infrastructure helps adoption of Rust. Without a good set of infrastructure tools, I know many won’t even consider Rust. It’s all well and good to make Rust’s learning curve easier, but if Rust isn’t even being considered serious enough to try to learn, it’s not going to help adoption much. There’s a couple small areas I’d like to utilize Rust at work, but it’s just not going to happen without the a good level of stable infrastructure, which makes me sad 
That’s not to say that there’s not already stuff out there heading the right direction, but I do feel it should be part of the vision to get Rust infrastructure more production ready.
Other than that, I definitely like these vision statements
