Hi,
I’ve got a pretty liberal view on these things: if there’s a group of people that want to document and work on a subject related to practices around Rust, form a group.
In general, I find it easier to not have these things under the nursery umbrella (mainly because of the administrative overhead), though. For example, Rust community is not run on rust-lang or the nursery, because that means we can freely assign members, start projects, etc, without involving the rust-lang organisation.
Best,
Florian
