Yeah, we are trying to get that one stabilized -- upstream `rustfmt`
is aware and working on it. More context at:
https://github.com/rust-lang/rustfmt/issues/6829
https://github.com/Rust-for-Linux/linux/issues/398
However, .rustfmt.toml already has a section of commented-out unstable options kept
as a reference for when they stabilize. Would it make sense to add `#imports_layout =
"Vertical"` there? If so, I can include it in v2.
That may be a bit confusing, because we still need to add the `//`
comments. And if you add them, then `rustfmt` will format properly,
i.e. you don't need the unstable option.
Put another way: the intended workflow is to add the `//` and then to
run `make ... rustfmt`.
I hope that clarifies!
