Thanks for preparing this PR! I'll finish a review by the end of tomorrow.

Don't have a clear idea about v0.3 yet. So I may drop the corresponding section.
The tutorial also needs some verification to make sure the instructions work.

I second to drop that section. Thinking of the history (evolution) of RoadMap v0.2, you can talk about what features are within consideration, but we'd better avoid promising its implementation.

I like the experience from ZeroMQ about How-ZeroMQ-Lost-Its-Road-Map, and nowadays a "release train" model is accepted widely (Rust, C++, Kafka, Flink, etc.).

Thanks for preparing the posts! Comments inline.

Also, I'm curious whether crates.io support a snapshot release so that we can verify all instructions really work well.

Thanks for the link! It's very interesting.

@tisonkun Thanks for your view. I have addressed some comments. I will improve it further when I can actually get the tutorial work.
